Look for cased character classes when deciding on case-fold-search, #'isearch lisp/ChangeLog addition: 2015-03-11 Aidan Kehoe <kehoea@parhasard.net> * isearch-mode.el: * isearch-mode.el (isearch-fix-case): Use the new #'no-case-regexp-p function if treating ISEARCH-STRING as a regular expression; otherwise, use the [[:upper:]] character class. * isearch-mode.el (isearch-no-upper-case-p): Removed. * isearch-mode.el (with-caps-disable-folding): Removed. These two haven't been used since 1998. * occur.el (occur-1): Use #'no-case-regexp-p here. * replace.el (perform-replace): Don't use #'no-upper-case-p, use #'no-case-regexp-p or (string-match "[[:upper:]]" ...) as appropriate. * simple.el: * simple.el (no-upper-case-p): Removed. This did two different things, and its secondary function (examining regular expressions) just became much more complicated; move the regular expression functionality to its own function, use character classes when examining non-regular-expressions instead. The code to look for character classes, and the design decision that this should be done, are from GNU, thank you Stefan Monnier. * simple.el (no-case-regexp-p): New. Given a REGEXP, return non-nil if it has nothing to suggest an interactive user wants a case-sensitive search. * simple.el (with-search-caps-disable-folding): * simple.el (with-interactive-search-caps-disable-folding): Update both these macros to use #'no-case-regexp-p.

This path contains test code for the new XEmacs
Drag'n'Drop code.

To test the code do the following:
1) call 'bash droptest.sh' to create the test files in /tmp
2) load and eval droptest.el in XEmacs
3) Try to do some internal DnD by using the sources and targets
   in the new buffer
4) Do some external DnD:
   4a) CDE: use dtfile and dtpad
   4b) MSWindows: well, explorer should do. But only file data
                  should work, and I don't know if the test
                  already handles this.

The misc-user-event now also responds as a button-x-event
to the event-* query functions.

The function of a drag is called dragdrop-drop-dispatch
as you can see in droptest.el. From within the function
you can access the actual misc-user-event through the
current-mouse-event variable.

Short description of the object part of a drop misc-user-event:
( TYPE . DATA )
TYPE is either the symbol dragdrop_MIME
     or the symbol dragdrop_URL

DATA is a list of URL strings if TYPE is dragdrop_URL
     if TYPE is dragdrop_MIME DATA is either a string
     which contains the MIME data, or it is a list of
     ( CONTENT-TYPE CONTENT-ENCODING MIME-DATA )
     CONTENT-TYPE is encoded for tm-view (list, first element type,
	rest key.value conses)
     CONTENT-ENCODING is a string
     MIME-DATA is a string

     CONTENT-TYPE and -ENCODING can be directly supplied to mime/viewer-mode.
