* 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
