Another vi update from Sterling Huxley:
- All of the ESC sequences are now in variables. This should make re-targeting for other terminals easier. - The initial screen draw does not force out every single column. Should be faster. - The place_cursor() routine trys to be smarter about moving the cursor. This is optional based on BB_FEATURE_VI_OPTIMIZE_CURSOR. - The 't' and 'f' intra-line positioning commands were added. They can now be used as targets in 'c' and 'd' commands, i.e., dfx - delete from dot to next 'x' dtx - delete from dot to the char before next 'x' - show_status_line() uses a static int checksum to remember what is currently displayed on the screen and not re-draw the status line unless it has changed. - Some of the code in refresh() was moved out to format_line(). refresh() trys to send out the smallest segment containing the changed chars rather than the whole line. - Added "flash" to the :set command to specify if error indication should be by flashing the screen or ringing the bell. - Changed the rawmode() routine so that it turns off the NL -> CR NL translation. On output of a NL, the OS will not add a CR. - If vi was started as "view", with global read-only mode, and another file is opened, the file is opened read-only rather than read+write.
