revsets: makes follow() supports file patterns (issue4757) (BC)
Before this patch, follow only supports full, exact filenames.
This patch makes follow argument to be treated like file
pattern same way like log treats their arguments.
It preserves current behaviour of follow() matching paths
relative to the repository root by default.
