(Ffile_name_as_directory, Fdirectory_file_name, Fexpand_file_name):
Call find_file_handler.
(syms_of_fileio): Set up Qfile_name_directory, etc.
(Fcopy_file): Call find_file_handler for newname as well as for filename.
(read_char): Use num_nonmacro_input_chars to decide on auto-save & gc.
Increment it when appropriate.
(record_auto_save): Use num_nonmacro_input_chars.
end of the heap, copying the data to it, and then freeing the
original bloc, just expand the original block. This saves a copy
and a call to sbrk, and also removes the large spike in memory
allocation that would occur when resizing large buffers. And it's
less code.
Don't modify comstyle inside that loop.
If string quotes don't match up, don't take value from OFROM;
instead, parse forward using scan_sexps_forward.
(scan_sexps_forward): Return value via a pointer passed in.
New element in state contains char addr of last comment-starter seen.
(Fparse_partial_sexp): Change call to scan_sexps_forward.
(syms_of_keyboard): New Lisp var.
(read_key_sequence): Use that instead of prev_event.
(read_char): Call read_char_menu_prompt here.
Accept 4 new args to pass to it. Include them in recursive call.
Don't delay before starting echo if prev_event was a mouse event.
Test for eof in batch mode now understands C is a Lisp_Object.
(read_key_sequence): Don't call it here; always call read_char.
Don't change last_event_buffer after a mouse menu input.
(read_char_menu_prompt): Arg PROMPT deleted.
Return nil if nothing to do.
(read_key_sequence): Keep track of prev_event.
Pass new proper args to read_char_menu_prompt.
(read_char_menu_prompt): New arg prev_event. Use Fx_popup_menu.
Handle any number of keymaps, not just LOCAL and GLOBAL.
Invert meaning of arg PROMPT. Test of menu_prompting was backwards.
(keymap_table): No longer static.
(Fx_popup_menu): Treat coords relative to spec'd window.
(single_keymap_panes): New function; contains guts of keymap_panes.
If a command binding for submenu has a prompt string starting with @,
make a separate pane for it at this level.
(keymap_panes): New function.
(Fx_popup_menu): Accept keymap or list of keymaps as MENU argument.
Accept mouse button event as POSITION argument.
