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
hg -q
hg help
hg -q help
hg add -h
hg add --skjdfks
hg help diff
hg help status
hg -q help status
hg help foo
hg skjdfks

exit 0
