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
"$TESTDIR/hghave" symlink || exit 80
hg init a
ln -s a link
cd a
echo foo > foo
hg status
hg status ../link
