This patch covers one big part of variable handling.
$ a=b foo
should be handled correctly.
$ a=b
is parsed OK, but the actual variable setting is not
yet written. Except for some weird exceptions related
to quoting rules, this code passes (matches ash behavior)
all the tests I threw at it.

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.
