Subject: 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.
