45e92ba2ce This patch from Evin Robertson <nitfol@my-deja.com> fixes export so it works. 
This way leaks memory, but oh well.  We will probably fix that when we get
around to doing local variables.

8cd16d8fd3 This syncs things with Vladimir's latest patches. Also gets 
rid of useless 'const int' declarations.

186bf1defc This is Vladimir's update to last_char_is(). Since 'char *' is 
the least common denominator, I modified it to use that (not const),
which will minimize the need for casting elsewhere.

83a2ae2184 More hush updates from Larry: 
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.

syslogd startup/shutdown messages as KERN.EMERG, but use
SYSLOG.INFO instead.

822c3837f9 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.

2dcfba7117 Larry's variant on Evin Robertson's fix to what I messed up 
trying to make job control work.  This fix makes it so that
hush doesn't error out when init hasn't set up job control,
as in when init=/bin/sh

044a72d0d5 Larry suggested using concat_path_file() would be an even safer bet 
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.

7526f035f4 Fix a buffer overflow. Which accounted for the size of the path, plus the the 
'/', plus the size of the test command.  It did not account for the terminating
NULL, which overwrote the end of the string.

bafd94f154 First pass at getting job control working. This gets the infrastructure 
in place, but something is still missing/wrong in there.  Testing with
'grep foo &' seems to put _hush_ into the background.  Pondering...
