Some pipes in tests lose the exit code of git processes, which can mask
unexpected behavior. Split these pipes up so that git commands are at
the end of pipes rather than the beginning or middle.

This title explains the mechanical changes the patch is making but not
the intent. Perhaps reword it to say something like:

    tests: avoid swallowing Git exit code upstream of a pipe

Can you say something about how you chose which tests to fix in this
patch? Is this fixing all such cases or only a subset? It looks like
it's only fixing "ls-files" and "verify-pack" invocations. If that's
the case, the commit message should explain that.

Also, missing sign-off.

Why is this change included in the patch? There is no Git invocation
upstream of a pipe here. While the cleanup itself may be desirable, it
doesn't belong in this patch.

Fixed - here is the new commit message (I changed the wording of your
header to fit within 50 chars):

    tests: don't swallow Git errors upstream of pipes

    Some pipes in tests lose the exit code of git processes, which can mask
    unexpected behavior like crashes. Split these pipes up so that git
    commands are only at the end of pipes rather than the beginning or
    middle.

    The violations fixed in this patch were found in the process of fixing
    pipe placement in a prior patch.

This actually should have been part of the "tests: standardize pipe
placement" patch, but I did "git commit --fixup=SHA" with the wrong
SHA. Fixed.
