Fix re: and glob: patterns in .hgignore (reported by Brad Schick) relglob: and relre: were already detected for a long time, so I kept this undocumented functionality, especially as it was already tested in test-hgignore.

#!/bin/sh

hg init
mkfifo p

hg serve --stdio < p &
P=$!
(echo lock; echo addchangegroup; sleep 5) > p &
Q=$!
sleep 3
kill -HUP $P
wait
echo .hg/* .hg/store/*
