Update some comments. Generate partial placeholders for the missing
builtins. Write builtin_umask. Properly treat exec without arguments
as a means to open/close files within the running script. Implement
"4<&-" that encodes for file descriptor closure.
- 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.
for 'which'. I ageed, so I whipped this up -- which revealed a bug in
concat_path_file. It turns out that that a '/' can be appended from
either the path _or_ the filename, but only the former was checked.

Minor improvements. Something is still broken with running
scripts via "hush filename". All the following are now handled
acceptably (matches ash, not bash).
if true; then echo foo1; fi
if
true; then echo foo2; fi
if true; false; then echo bar; else echo foo3; fi
if true || false; then echo foo4; fi
