commit b1db7f4bd7df1005d9d385606229356f3ead0d24
Author: G. Branden Robinson <address@hidden>

    [hdbtl] Robustify test against crazy pathnames.
    
        * contrib/hdtbl/examples/test-hdtbl.sh.in: Quote expansions of
        variables that are under external control; specifically, the
        Automake variables @abs_top_builddir@ and @GHOSTSCRIPT@ could
        conceivably have space characters in them on slap-happy systems.
        Had we been wiser, we'd all be using descendants of the rc shell
        now...
