* add set-auto-mode() to (re)select best mode for buffer
* add set-next-mode() on M-m to cycle appropriate buffer modes
* add set-previous-mode()
* add default_mode and saved_mode in buffers to improve mode switching
* add dired mode probing and store st_mode in buffer to detect directories
* add charset, eol_type and buffer in ModeProbeData
* clean mode selection and window buffer attachment (needs more work)
* compute sorted list of appropriate modes in probe_mode
* convert charset and eol_type in mode_probe
* add signatures in buffer priv_data to perform save casts
* move BufedState to b->priv_data, protect mode specific functions
add bufed_mode_probe function, cycling through modes comes back to bufed mode
* move DiredState to b->priv_data, protect mode specific functions
add dired_mode_probe function, cycling through modes comes back to dired mode
* add heading line in dired buffer with directory spec
* protect shell-mode specific functions.
* restart shell in shell() command if exited
* some cosmetics changes (remove useless __unused__, missing messages ...)
* change tab-size to tab-width
* make tab-width a buffer variable
* add fill-column buffer variable
* add set-fill-column on C-x f
* add default-tab-width and default-fill-column global variables
* force indent-tabs-mode in makefile mode
* force tab-width to 8 in shell output buffers
* added colorize_func in ModeDef struct
* removed mode_init functions for most language modes
* other small improvements in mode_probe functions
* no need for get_basename in mode_probe functions
* pass ModeDef pointer to mode_probe functions
* add extensions field to mode structure
* rename ascii mode to binary mode
* rename mode variables and fields to more specific names
added eb_find_new -> find a buffer by name, create one from flags if not found.
qe_register_cmd_table takes ModeDef* instead of mode name
do_global_set_key -> do_set_key with local/global flag
added local-set-key
reuse *bufed* buffer if one exists
bind increase/decrease-width commands from command definition
cosmetics, comments, remarks
renamed kill buffers from *yank* to *kill-%d*
save QErrorContext in parse_args, load_all_modules:
improves readability in *messages* buffer
fixed qe_init to fall back from x11 display to terminal session upon failure
renamed canonize to canonicalize
added crude support for ~user -> /home/user
added win32 specific stuff in basename
added C-/ as an alias for C-_
some cosmetics, moved code
create files with mode 0644 in raw_save_buffer
untabified, removed redundant spaces
modified code generators to the same effect
added Makefile mode: makemode.c
added HTML source mode: htmlsrc.c
added more dependencies in Makefile
added styles for HTML source coloring:
html-comment, html-string, html-script, html-entity, html-tag
no longer rely on \n at end of line in c_colorize_line
