keyword: allow keyword expansion on clone
If [keyword] filename patterns are specified in a global hgrc
keywords will be expanded in clone.
This behaviour is more consistent but also more dangerous.
Specifying global, and thus more complicted, [keyword] patterns
might slow things down as well.
Mention this in help?
