Subject: [PATCH 02/11] Revert "Read exclude patterns from .gitignore in
 absence of user-provided patterns (#344) (#345)"

This reverts commit aa6fcd281d2a6f963a99ee6f3c5055876f5a54f5.

After further thought, the --exclude flag and .gitignore file
have different responsibilities and mixing them will surprise
some users.
