* This patch covers one big part of variable handling.andersen2001-05-151-5/+49
| | | | | | | | | | | | | | | | | | $ 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! - Larry git-svn-id: svn://busybox.net/trunk/busybox@2644 69ca8d6d-28ef-0310-b511-8ec308f3f277
