Fix bug when processing parent gitignore files.

This particular bug was triggered whenever a search was run in a directory
with a parent directory that contains a relevant .gitignore file. In
particular, before matching against a parent directory's gitignore rules,
a path's leading `./` was not stripped, which results in errant matching.

We now make sure `./` is stripped.

Fixes #184.
