Clean up #'read-quoted-char, support help-event-list there. lisp/changeLog addition: 2015-03-14 Aidan Kehoe <kehoea@parhasard.net> * simple.el (quoted-insert): Update the docstring here, syncing GNU's, especially mentioning read-quoted-char-radix. * cmdloop.el: * cmdloop.el (read-quoted-char-radix): Move this up here, outside the functions. * cmdloop.el (read-function-key-map): New label, reading and replacing characters from function-key-map if appropriate. * cmdloop.el (read-quoted-char): Multiple changes: -- Take advantage of help-event-list, but be careful not to have any keystrokes with character equivalents in it, so the user can type C-q C-h and have the expected result. -- Use function-key-map, as does #'read-char and #'read-exclusive-char, helpful for character composition under X11. -- Pop up the help window ourselves if, e.g. F1 arrives on a TTY via function-key-map, event-stream won't have done it. -- Error if no keystroke that can be converted into a character is specified, don't just insert ?\x00 as we used to and as does GNU -- Use #'digit-char-p instead of reimplementing it. -- Fix a bug of mine where I wasn't consistent about treating character codes as Unicode.

278 You may also type up to 3 octal digits, to insert a character with that code. 278 With argument, insert ARG copies of the character.

280 If the first character you type after this command is an octal digit,
281 you should type a sequence of octal digits which specify a Unicode character.
282 Any nondigit terminates the sequence. If the terminator is a RET,
283 it is discarded; any other terminator is used itself as input.
284 The variable `read-quoted-char-radix' specifies the radix for this feature;
285 set it to 10 or 16 to use decimal or hex instead of octal.
