rhg: fix the bug where sparse config is interpreted as relglob instead of glob
relglob apparently (in contrast with relpath) matches everywhere in the tree,
whereas glob only matches at the root.
The python version interprets these patterns as "glob" (see
"normalize(include, b'glob', ...)" in match.py)
