 Right now, non-annexed files get passed through the `annex` clean/smudge filter (see [[forum/Adding_files_to_git__58___Very_long___34__recording_state_in_git__34___phase]]).  It would be better if `git-annex` configure the filter only for the annexed unlocked files, in the `.gitattributes` file at the root of the repository.

+It immediately occurs to me that the proposal would break this:
+
+	git annex add foo
+	git annex add bar
+	git annex unlock bar
+	git mv bar foo
+	git commit -m add
+
+Since foo was a locked file, gitattributes would prevent from being
+smudged, so the large content that was in bar gets committed directly to git.
+
+The right solution is to improve the smudge/clean filter interface to it's
+not so slow, which there is copious discussion of elsewhere.
