fix v6 deadlock with git 2.1.4

Browse source 
I don't know why git diff --raw would run the clean filter, but it did
with this version of git. Perhaps it is cleaning the file to generate the
diff to search with -G?  But then why would newer gits not run the clean
filter?

It caused git annex to deadlock because the keys database was locked
and ran a git command that ran git-annex, which tried to read from the
keys database.
