glob:<directory> patterns match the files in that directory.
This makes the behaviour of glob: patterns more consistent:
hg status glob:dir and hg status -I glob:dir will match
the same files.
It's also consistent with the fact that {rel,}path patterns
recursively match the contents of a directory.
#!/bin/sh
mkdir t
cd t
hg init
echo a > a
hg add a
hg commit -m "test" -d "1000000 0"
hg verify
hg parents
hg status
hg rollback
hg verify
hg parents
hg status
