52a97ca00c Some more cleanups. Of special importance, never free a pipe 
that still has running jobs.  Instead, we ignore it and expect
it to be cleaned by the background job stuff.

8a646dd293 This commit guts lash, restoring it to what it was originally intended to do, 
just be a simple command line interpreter with basic pipe, redirect, and job
control.  For all the more fancy things, people should use hush or ash.

04407e522b Another hush update from Larry: 
Fixes the interaction between if/then/else/fi syntax and variables.
    I planned to do it right from the beginning, but my implementation
    was buggy.  Also adds the relevant test cases.  Also adds some old
    Matt Kraai variable test cases that got left out somehow.

    > I write this special for variable HUSH_VERION=0.01)

    > 6) next add integraion with libbb

Valdimir's patch missed two cases of local variable handling
    FOO=bar
    export FOO=baz
    unset FOO
and
    export FOO=bar
    FOO=baz
which were working before, so I fixed those two cases.

bfae2529b8 It turns out job control in both hush and lash was broken by the 
signal handling in cmdedit.c.  Disabling it makes the shells behave
themselves again.  hush isn't quite there, but is getting close...

78a7c99f7f 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.

If someone now writes set_local_var(), and updates lookup_param()
to match, we can claim success!

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.

    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).

6faae7deb4 Commit Vladimir's latest cmdedit. I modified it slightly to ensure 
parse_prompt() would be called before cmdedit_init(), since cmdedit_init()
calls cmdedit_setwidth() which uses cmdedit_prmt_len, which is set by
parse_prompt().  Also, added a mod, so very narrow terminals should now wrap
properly...  This is working very nicely for me -- Vladimir has done some
very good work.

67991cf824 This patch, put together by Manuel Novoa III, is a merge of work 
done by Evin Robertson (bug#1105) and work from Manuel to make
usage messages occupy less space and simplify how usage messages
are displayed.

af4ac77d9d Apply a patch from Larry Doolittle to add "-all" and "-none" switches 
to multibuild.pl.  I did a little formatting adjustments to make it
_very_ obvious when things stop working.  I also removed the USE_PROCFS
config option -- just do the right thing when USE_DEVPS_PATCH is enabled.

e9f07fb6e8 Another sh.c patch from Larry Doolittle. This makes redirects work properly 
with non-forking shell builtins.  Especially helpful for "read".  This patch
also beautifies builtin_fg_bg, clarifies the problems with
run_command_predicate, makes if/then/else support the default, and corrects the
sense of the BB_FEATURE_SH_ENVIRONMENT comment.

86349776d0 Ok, this is a pretty major update to sh.c. I renamed all the variables and 
function names to conform with the style guide.  I also did a lot of work on
the if-then-alse-fi logic and added prototype (i.e. it segfaults when enabled)
line continuation support.

Furthermore, this patch includes Larry Doolittle's work on restructuring some
of the data structures that represent the job and child_program, allowing
several simplifications and fixing several bugs.
