Fix dirstate.changes for ignored directories.
Do a second walking pass to examine any leftover files in the dirstate
map that are in the .hgignore file but match our search criteria.
This fixes the case of entire directories never being examined due to
their presence in the .hgignore file, and should hopefully not add any
significant overhead.
