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...

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!

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.

acceptably (matches ash, not bash).

true; then echo foo2; fi
if true; false; then echo bar; else echo foo3; fi
if true || false; then echo foo4; fi

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.

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).
