Chirpy!

A number of our pages were failing to display with webapp.enable_gzip=1 in
chirpy.ini, as it would print a small amount of gzipped output and then
output an error page complaining about wide characters and gzip.

Perhaps the gzip code in util/gzip.pl could be amended with a patch similar
to this:
