I think this is an idea to solve a good problem, but if we go
this route, the need for us to worry about expiring lost-found
entries would become more urgent, I suspect.
And when you think about expiring lost-found entries, another
possible solution emerges. If we teach git-prune to remove the
corresponding entry from lost-found/other when it removes a
loose blob from the object store, then we can easily and safely
do this instead:
$ cat .git/lost-found/other/* |
xargs -r git grep 'the word to look for'

Why? AFAICT lost+found/ has to be cleaned by people. So if you look for
something, you say "git fsck --lost-found", and once you found it, it's
time for "rm -rf .git/lost-found".

Well, it is not only for grepping. In my case, I could get away by this:
$ ls -lrt $(grep -l filter_subdir .git/lost-found/other/* |
sed "s/^.*other\/\(..\)/.git\/objects\/\1\//")
IOW I found the loose dangling objects which matched a keyword, and sorted
them by time.
In other cases, though, I wanted to see the size.
But what the whole thing boils down to: After finding dangling objects,
you are much more likely using git tools on non-blobs than on blobs, and
vice versa.

P.S.: I fully forgot to mention that happily, I did "git add -u" sometime
before "git reset --hard", otherwise I would have been lost.
