* support 3 types of end of line: Unix, Dos and old style Mac
* detect eol type automatically in detect_charset
* set buffer eol_type together with charset
* transparently convert eol sequence to \n upon reading buffers
characters in eb_nextc().
* transparently convert \n to eol sequence in eb_encode_uchar()
* handle eol types in convert-file-buffer-coding-system: either preserve
current value or force it via charset suffix -unix, -doc and -mac
* change read_charset() to accept eol_type suffix
* add eol_type and eol_char to CharsetDecodeState
* change charset methods to take CharsetDecodeState instead of charset pointers
* display eol_type in mode line if not unix
* prepare support for eol_type support by making char encoding buffer specific
* fix small bugs and unsafe cases.
* fix bug in eb_goto_pos for EBCDIC charsets
* add qe_isaccent() to test for combining marks
* add do_combine_char() command to insert or remove combining marks
* fix some display glitches involving combining marks
* add expand_ligature() and combine_accent() to handle simple ligatures
* change do_what_cursor_position() to display combining marks
* add free_font_cache()
* add css_free_colors()
* add unload_ligatures()
* add --free-all cmd line option to free memory upon exit for valgrind
* tty.c: fix off by 3 size in qe_realloc. Should be typed
* qe.c: fix invalid pointer reference upon destroying transient buffer
* use qe_mallocz for all structures
* prevent spurious uses of malloc/free/realloc
* pass pointers to pointers to all deletion functions
* use consistent patterns for list deletions
* add more dependencies in Makefiles
* 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
* changed keytostr to buf_put_key using buf_t structure
* changed keys_to_str tp buf_put_keys using buf_t structure
* add buf_attach to initialize buf_t with non empty buffer
* simplify qe_list_bindings with inherit argument
* styles_buffer hold static style info for each character in the buffer
* new buffer flags to create styles buffers with 1, 2 or 4 bytes per char
* copy static styles to the kill_ring and pasted them style enabled buffers
* preserve static styles in convert-buffer-file-coding-system
* display style bytes in bufed list
* add commands set-region-color, set-region-style, drop-styles
* use bit 2 in b->save_log to suspend callbacks and logging during transient
undo phase.
* dispatch callbacks before buffer modification (eb_delete)
* this fixes bugs in the undo system where some offsets were not properly
updated, color buffer was shifted, cursor would get lost and sometimes
crash would follow.
* buffer colors are not undone properly
* pass extra int argument to buffer callbacks
* make eb_offset_callback more generic: handle edge effect via extra arg.
edge effect causes offset to move upon insertion at current value
* add new log variables log_last_char and last_log.
use these to coalesce consecutive log records and make undo more efficient
* add new command "redo" on C-x C-_ and C-x r
* fix undo glitches in the process buffer, update cursor correctly upon redo
* determine hex dump width from max char value in buffer
* display byte offset in margin instead of char offset
* accept 0x1f in text-mode
* no longer output octal char value if not ASCII
* make eb_insert_buffer return the number of bytes inserted
* reset page bits upon charset change
* add eb_delete_nextc: delete one encoded character at offset
* add eb_insert_uchar: insert a unicode character with encoding
* add eb_insert_utf8_buf: insert a utf8 encoded buffer with conversion
* make eb_printf insert utf8 bytes with conversion
* add eb_insert_buffer_convert: copy chars between buffers with charset
conversion
* handle charset conversion correctly in various places
* insert wide caracters from hex mode
* create most buffers as BF_UTF8 by default
* set kill-buffer charset to that of kill source
* convert charsets when yanking
* handle charsets in search/replace system
* 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
- fixed crash bug in qe_unregister_binding1, missing indirection in qe_free argument
- added Darwin specific definition for 'end' (this is an ugly patch, to be removed)
- fixed crash bug in qe_set_variable, missing indirection in qe_free argument
added charset methods for buffer line and position computations
added QECharset fields for char_size and variable_size indicator
use charset's eol_char to count lines in buffers: this should fix EBCDIC support
added support for ucs2 and ucs4 little and big endian encodings
charset's decode_func call no longer be NULL
eb_nextc and eb_prev now require non NULL third parameter
added command apropos(string)
added command show-bindings(cmd_name)
moved describe-bindings to extras.c
added qe_get_prototype(CmdDef *d, char *buf, int size);
added an extra argument to qe_get_variable() to produce value as source
fixed typo on window variable window-height
fixed type mismatch on mode variable mode-name
added var_domain string array
added strquote conversion function with simplistic implementation
added history tags for all commands
