handles all the basic stuff (for, case/esac, while, if/then/else), and
is very small (adds just 38k on x86). It is not as rigorously correct
about Bourne semantics as bash, but for most things it is quite
workable. There is still some work to be done to further shrink it (it
has its own globbing functions instead of using the libc ones, for
example), but it is quite usable as is.

commented out instead of simply deleted (so they could be re-enabled)
and the builtins all work. This adds 72k.

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.

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.

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.

signal handling in cmdedit.c. Disabling it makes the shells behave
themselves again. hush isn't quite there, but is getting close...

$ 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!

xgetcwd, but did not check the return for a NULL, and then continued
to call strlen on the NULL when the cwd had been removed from under it.

This way leaks memory, but oh well. We will probably fix that when we get
around to doing local variables.

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.

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
