* add indent_func method in ModeDef
* make c-indent-region more general as indent-region
* add c-forward-conditional on M-]
* add c-backward-conditional on M-[
* add c-list-conditionals on M-i
* use trick to disambiguate M-[ and CSI sequences
* add eb_is_in_indentation(b, offset)
* fix c-mode indentation of case and default lines
* add tabify-buffer and tabify-region
* add untabify-buffer and untabify-region
* make eb_delete and eb_delete_range return actual number of bytes removed
* simplify some deletions with better use of eb_delete_xxx functions
* 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 ...)
* add do_describe_buffer to enumerate all buffer attributes in a popup
* analyze buffer contents and show map of bytes present in buffer
* this eases debugging when non ASCII bytes are hard to see
* 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
* 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
* add command delete-horizontal-lines in extras.c
* simplify do_delete_horizontal_space
* bind backward-paragraph and forward-paragraph to M-[ and M-]
* M-[ binding is not effective in terminal because it clashes with ansi
escape sequences
* comment some key bindings for compatibility
* improve compute_crc: no longer fail on simple 1 character transposition
* remove limitations on block size in do_transpose
* preserve styles in do_transpose
* 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
