This script already relies on the assumption that nobody sane would
create a directory named ".git" that is not a git repository, and
this loosens the assumption that nobody would create a file named
".git", either.  So I would think it is a sane thing to do, but just
in case if the area expert has better ideas, I am forwarding it.
