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

9f8caf134f Fix $(...) construction. Noted and patched by Larry Doolittle

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...

1c8a59ab95 Use the current pgrp, not pid, when resetting the foreground process group.

e67c3ce327 Another update from Larry:
Makes hush return code equal to that of the last command executed.
    Fixes the mode where input comes from a file.

4ed5e37d4b Another hush update from Larry:
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

af44a0e8f4 An update to hush from Larry:
It should recover more smoothly from syntax errors, and it now
    has a decent guess when the reserved word construct is over
    (or not) to control execution and prompting.  I took out all the
    redundant standalone test copies of libbb routines, but left in a
    hook so I can include those for my testing.  I'll post that include
    file on my web site.

25f2703015 This is the initial checkin of Larry Doolittle's hush.c, using his
April 25, 2001 snapshot, adjusted a bit by me so it has cmdedit support.

This checkin also removes sh.c.  In the future sh.c will be a symlink to
your shell of choice.  For now, this symlink will default to pointing to
lash.c (as in the past).  If you change the symlink to point to hush.c,
then thats what you will get.  This symlink business is a temporary situation,
which will be cleaned up Real Soon Now(tm).

ed424dbf1d Some patches from Gennady Feldman. Fixed a glob problem such that
'ls *.h Config.h' works.  Fixed a silly typo with fg/bg process control.
Made cmdedit exit sanely when it cannot read input.

f594986b37 - Changed name of BB_FEATURE_SIMPLE_PROMPT to BB_FEATURE_SH_SIMPLE_PROMPT
- Set BB_FEATURE_SH_STANDALONE_SHELL and BB_FEATURE_SH_APPLETS_ALWAYS_WIN to
   be off by default
 - Set BB_FEATURE_SH_SIMPLE_PROMPT to be on by default
 - Added some more magic to the Olympus section to make all the dependencies
   on the shell, cmdline editing, tab completion and friend work properly.
 - Tidied up the Olympus section with some whitespace. Checked the various
   scrips that parse through there and the extra whitespace shouldn't break
   anything.
