This transformation doesn't look correct. COPY already holds the result of a git-rev-parse invocation:

    COPY="$(git rev-parse --verify me/copy)" &&

so passing it to test_cmp_rev() -- which applies its own git-rev-parse invocation -- doesn't make sense.

As mentioned in my review of the other patch, this is not a valid use of test_must_fail().
