Is there a means to have fsck to a truly full check on the sanity of a
repo?

git fsck --full

RTFM, please.

Right... sorry for the noise, I mismatched --strict for --full in a
script.

BTW, the short help for fsck at --full only says "consider objects in
alternate repositories".

Until I read this thread, I didn't realize you needed --full to check
objects in packs.

Since just every git repository I ever use has 99%+ of it's objects in
packs, this means every time I've run "git fsck" it's essentially been
a no-op and I didn't know it. I imagine this is a common confusion.

Also, having --full mean both "check alternate object pools", and "check
objects in packs" seems to be rolling up two orthogonal issues.

But anyway, here is a patch that at least fixes the short option help to
match the manual and the current behavior:

Subject: [PATCH] Update git fsck --full short description to mention packs

The '--full' option to git fsck does two things:

  1) Check objects in packs
  2) Check alternate objects

This is documented in the git fsck manual; this patch reflects that in
the short git fsck option help message as well.
