Subject: Another hush update from Larry:

    Minor improvements.  Something is still broken with running
    scripts via "hush filename".  All the following are now handled
    acceptably (matches ash, not bash).

    if true; then echo foo1; fi
    if
     true; then echo foo2; fi
    if true; false; then echo bar; else echo foo3; fi
    if true || false; then echo foo4; fi

	  - Larry
