+git grep doesn't use an index per se, but is probably faster
+than `find` at least sometimes. And probably somewhat faster than things
+involving `git-annex find` too.
+
+It's unfortunate that `git grep` doesn't search on the content of symlink
+texts, so that can't be used to find locked files.
+

+
+       git annex find --format '${key}\n' | grep SHA256E-s320029--488e29f5584ba4e474db95aa42fbb58ddb92f2a59bc0b24a91171acb4d8f4828.png
