event-stream.c, support help-event-list as does GNU.
src/ChangeLog addition:
2015-03-14 Aidan Kehoe <kehoea@parhasard.net>
Add support for GNU's help-event-list here, useful for accepting
F1 and C-h as the help character at the same time.
* event-stream.c:
* event-stream.c (echo_key_event):
Be better about calculation, comments here, in passing.
* event-stream.c (help_char_p): New.
* event-stream.c (execute_help_form):
There's no need to reset the command builder here; the code that
did relied on zero-termination, which we can't anymore, and did
not actually discard the help character. Remove this.
* event-stream.c (Fnext_event): Use help_char_p ().
* event-stream.c (command_builder_find_leaf_no_jit_binding):
Use help_char_p ().
* event-stream.c (vars_of_event_stream):
Make help-event-list available.
man/ChangeLog addition:
2015-03-14 Aidan Kehoe <kehoea@parhasard.net>
* lispref/help.texi (Help Functions):
Document help-event-list, just added.
lisp/ChangeLog addition:
2015-03-14 Aidan Kehoe <kehoea@parhasard.net>
* cus-start.el (all): Describe help-event-list for Custom.
* keydefs.el (help-event-list): Initialise it.
