* 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
* mode initializers should call text-mode-init to register ccallback
for s->offset and s->top_offset, and other generic stuff.
* this is error prone, should simplify this with base_mode property and
keep unmapped windows lingering to get rid of ModeSavedData handlers
* 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
* 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
* fix utf8 issues with completion, no longer match partial characters
* fix missing focus on completion popup upon first display
* close completion popup on space/tab
* 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
* org_scan_chunk: no longer checks for space before chunk
* org_colorize_line: better check for heading line
* org_colorize_line: check for chunks after white space
* simplify do_org_todo
* add new functions:
- do_org_mark_element (M-h)
- do_org_mark_subtree (C-c @)
* improve colorizer:
- handle blocks (with coloring for lisp src)
- handle TeX escapes, macros
- handle properties, wiki syntax for rich text
* simplify header line handling, and other such utility functions
* fix org-insert-heading, org-promote/demote, org-promote/demote-substree
* fix org-meta-return
* add org-move-subtree-up/down
* remove standard init_mode function
* 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
* show new charset in set-buffer-file-coding-system
* do not use double negative if/else constructs
* ignore new extensions in file_completion
* pass filename to probe_mode, no longer need buffer reference
* fix support for line drawing characters in utf8 shell window
* 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
* filter control characters and non BMP1 code points
* new mode specific modeline
* do not space out single width glyphs (not very readable)
* eb_get_char_offset: add validation on offset argument
* eb_get_char_offset: align offset argument on character boundary
