       scripts/squid_redirect: Move % unescaping into the zap pattern
                               matching function so that $words[0]
                               remains undamaged. Previously a %20 in an
                               input URL which hit a PASS rule (or no rule)
                               transmuted into a bare space, and other
                               nasty chars could do likewise - I imagine
                               a %0a would really break stuff.
                               Rod Savard reported this issue, which
                               breaks chained redirectors, on 29mar2004.

       scripts/squid_redirect: Jean-Pierre Radley reports that the
                               /usr/bin/env trick fails because SCO
                               OpenServer 5.0.x has /bin/env, not
                               /usr/bin/env. So I've reverted to the
                               older, simpler system, undoing the
                               suggestion of Petri T. Koistinen.
       Mykefile: Use $HOMEHOST instead of hardwiring "amadeus".
