Update tests that have started failing because of changed design decisions.
2011-11-09 Aidan Kehoe <kehoea@parhasard.net>
Update some tests that have started failing because of some
changed design decisions.
* automated/lisp-tests.el (eq):
(type-of 42) now returns the symbol fixnum.
* automated/lisp-tests.el (needs-lexical-context):
(function ...) doesn't create a lexical context, and this is now the
case in interpreted as well as in compiled code.
* automated/mule-tests.el (featurep):
Silence messages when byte-compiling files; if a file doesn't have
the escape-quoted coding cookie, it will now have the
raw-text-unix coding cookie, look for that instead of looking for
the absence of the escape-quoted coding cookie.

| 1401 DEFVAR_SPECIFIER ("default-toolbar", &Vdefault_toolbar /* | |
| 1402 Specifier for a fallback toolbar. | |
| 1403 Use `set-specifier' to change this. | |
| 1404 | |
| 1405 The position of this toolbar is specified in the function | |
| 1406 `default-toolbar-position'. If the corresponding position-specific | |
| 3025 | 1407 toolbar (e.g. `top-toolbar' if `default-toolbar-position' is `top') |
| 428 | 1408 does not specify a toolbar in a particular domain (usually a window), |
| 1409 then the value of `default-toolbar' in that domain, if any, will be | |
| 1410 used instead. | |
| 1411 | |
| 1412 Note that the toolbar at any particular position will not be | |
| 1413 displayed unless its visibility flag is true and its thickness | |
| 1414 \(width or height, depending on orientation) is non-zero. The | |
| 1415 visibility is controlled by the specifiers `top-toolbar-visible-p', | |
| 1416 `bottom-toolbar-visible-p', `left-toolbar-visible-p', and | |
| 1417 `right-toolbar-visible-p', and the thickness is controlled by the | |
| 1418 specifiers `top-toolbar-height', `bottom-toolbar-height', | |
| 1419 `left-toolbar-width', and `right-toolbar-width'. | |
| 1420 | |
| 1421 Note that one of the four visibility specifiers inherits from | |
| 1422 `default-toolbar-visibility' and one of the four thickness | |
| 1423 specifiers inherits from either `default-toolbar-width' or | |
| 1424 `default-toolbar-height' (depending on orientation), just | |
| 1425 like for the toolbar description specifiers (e.g. `top-toolbar') | |
| 1426 mentioned above. | |
| 1427 | |
| 1428 Therefore, if you are setting `default-toolbar', you should control | |
| 1429 the visibility and thickness using `default-toolbar-visible-p', | |
| 1430 `default-toolbar-width', and `default-toolbar-height', rather than | |
| 1431 using position-specific specifiers. That way, you will get sane | |
| 1432 behavior if the user changes the default toolbar position. | |
| 1433 | |
| 1434 The format of the instantiator for a toolbar is a list of | |
| 1435 toolbar-button-descriptors. Each toolbar-button-descriptor | |
| 1436 is a vector in one of the following formats: | |
| 1437 | |
| 1438 [GLYPH-LIST FUNCTION ENABLED-P HELP] or | |
| 1439 [:style 2D-OR-3D] or | |
| 1440 [:style 2D-OR-3D :size WIDTH-OR-HEIGHT] or | |
| 1441 [:size WIDTH-OR-HEIGHT :style 2D-OR-3D] | |
| 1442 | |
| 1443 Optionally, one of the toolbar-button-descriptors may be nil | |
| 1444 instead of a vector; this signifies the division between | |
| 1445 the toolbar buttons that are to be displayed flush-left, | |
| 1446 and the buttons to be displayed flush-right. | |
| 1447 | |
| 1448 The first vector format above specifies a normal toolbar button; | |
| 1449 the others specify blank areas in the toolbar. | |
| 1450 | |
| 1451 For the first vector format: | |
| 1452 | |
| 1453 -- GLYPH-LIST should be a list of one to six glyphs (as created by | |
| 1454 `make-glyph') or a symbol whose value is such a list. The first | |
| 1455 glyph, which must be provided, is the glyph used to display the | |
| 1456 toolbar button when it is in the "up" (not pressed) state. The | |
| 1457 optional second glyph is for displaying the button when it is in | |
| 1458 the "down" (pressed) state. The optional third glyph is for when | |
| 1459 the button is disabled. The optional fourth, fifth and sixth glyphs | |
| 1460 are used to specify captioned versions for the up, down and disabled | |
| 1461 states respectively. The function `toolbar-make-button-list' is | |
| 1462 useful in creating these glyph lists. The specifier variable | |
| 1463 `toolbar-buttons-captioned-p' controls which glyphs are actually used. | |
| 1464 | |
| 1465 -- Even if you do not provide separate down-state and disabled-state | |
| 1466 glyphs, the user will still get visual feedback to indicate which | |
| 1467 state the button is in. Buttons in the up-state are displayed | |
| 1468 with a shadowed border that gives a raised appearance to the | |
| 1469 button. Buttons in the down-state are displayed with shadows that | |
| 1470 give a recessed appearance. Buttons in the disabled state are | |
| 1471 displayed with no shadows, giving a 2-d effect. | |
| 1472 | |
| 1473 -- If some of the toolbar glyphs are not provided, they inherit as follows: | |
| 1474 | |
| 1475 UP: up | |
| 1476 DOWN: down -> up | |
| 1477 DISABLED: disabled -> up | |
| 1478 CAP-UP: cap-up -> up | |
| 1479 CAP-DOWN: cap-down -> cap-up -> down -> up | |
| 1480 CAP-DISABLED: cap-disabled -> cap-up -> disabled -> up | |
| 1481 | |
| 1482 -- The second element FUNCTION is a function to be called when the | |
| 1483 toolbar button is activated (i.e. when the mouse is released over | |
| 1484 the toolbar button, if the press occurred in the toolbar). It | |
| 1485 can be any form accepted by `call-interactively', since this is | |
| 1486 how it is invoked. | |
| 1487 | |
| 1488 -- The third element ENABLED-P specifies whether the toolbar button | |
| 1489 is enabled (disabled buttons do nothing when they are activated, | |
| 1490 and are displayed differently; see above). It should be either | |
| 1491 a boolean or a form that evaluates to a boolean. | |
| 1492 | |
| 1493 -- The fourth element HELP, if non-nil, should be a string. This | |
| 1494 string is displayed in the echo area when the mouse passes over | |
| 1495 the toolbar button. | |
| 1496 | |
| 1497 For the other vector formats (specifying blank areas of the toolbar): | |
| 1498 | |
| 3025 | 1499 -- 2D-OR-3D should be one of the symbols `2d' or `3d', indicating |
| 428 | 1500 whether the area is displayed with shadows (giving it a raised, |
| 1501 3-d appearance) or without shadows (giving it a flat appearance). | |
| 1502 | |
| 1503 -- WIDTH-OR-HEIGHT specifies the length, in pixels, of the blank | |
| 1504 area. If omitted, it defaults to a device-specific value | |
| 1505 (8 pixels for X devices). | |

| 1590 *Height of the default toolbar, if it's oriented horizontally. | |
| 1591 This is a specifier; use `set-specifier' to change it. | |
| 1592 | |
| 1593 The position of the default toolbar is specified by the function | |
| 1594 `set-default-toolbar-position'. If the corresponding position-specific | |
| 1595 toolbar thickness specifier (e.g. `top-toolbar-height' if | |
| 3025 | 1596 `default-toolbar-position' is `top') does not specify a thickness in a |
| 428 | 1597 particular domain (a window or a frame), then the value of |
| 1598 `default-toolbar-height' or `default-toolbar-width' (depending on the | |
| 1599 toolbar orientation) in that domain, if any, will be used instead. | |
| 1600 | |
| 1601 Note that `default-toolbar-height' is only used when | |
| 3025 | 1602 `default-toolbar-position' is `top' or `bottom', and `default-toolbar-width' |
| 1603 is only used when `default-toolbar-position' is `left' or `right'. | |
| 428 | 1604 |
| 1605 Note that all of the position-specific toolbar thickness specifiers | |
| 1606 have a fallback value of zero when they do not correspond to the | |
| 1607 default toolbar. Therefore, you will have to set a non-zero thickness | |
| 1608 value if you want a position-specific toolbar to be displayed. | |
| 1609 | |
| 1610 Internally, toolbar thickness specifiers are instantiated in both | |
| 1611 window and frame domains, for different purposes. The value in the | |
| 1612 domain of a frame's selected window specifies the actual toolbar | |
| 1613 thickness that you will see in that frame. The value in the domain of | |
| 1614 a frame itself specifies the toolbar thickness that is used in frame | |
| 1615 geometry calculations. | |
| 1616 | |
| 1617 Thus, for example, if you set the frame width to 80 characters and the | |
| 1618 left toolbar width for that frame to 68 pixels, then the frame will | |
| 1619 be sized to fit 80 characters plus a 68-pixel left toolbar. If you | |
| 1620 then set the left toolbar width to 0 for a particular buffer (or if | |
| 1621 that buffer does not specify a left toolbar or has a nil value | |
| 1622 specified for `left-toolbar-visible-p'), you will find that, when | |
| 1623 that buffer is displayed in the selected window, the window will have | |
| 1624 a width of 86 or 87 characters -- the frame is sized for a 68-pixel | |
| 1625 left toolbar but the selected window specifies that the left toolbar | |
| 1626 is not visible, so it is expanded to take up the slack. | |
