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.

#!/bin/sh

hg init

echo "Is there an error message when trying to diff non-existing files?"
hg diff not found

echo "Is there an error message when trying to add non-existing files?"
hg add not found
