It would be nice to have an option to exclude version control system (VCS) directories in a recursive grep.
This can be done effectively with these options
--exclude-dir=.bzr --exclude-dir=CVS --exclude-dir=.git
--exclude-dir=.hg --exclude-dir=.svn
But having a single, simple option would be preferred.
tar already has this
--exclude-vcs
Exclude version control system directories.
