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.
