Good catch for the test, but I think we can make the sed regexp simpler, as we
can leave out the second "[0-9a-f]"? (git reflog |sed
"s/^[0-9a-f]*/OBJID/" works here)

The implication of that we'd also match if there is no object id at
all at the beginning,
which sounds fine.

I shortly debated the idea to just cut off anything before the first
space and then expect
"HEAD@{0}: pull --rebase . ff: Fast-forward" only, but why cut off
what we produce
in the first place?

    git reflog --format="%s" -1 >actual &&
    echo "pull --rebase . ff: Fast-forward" >expect &&
    test_cmp expect actual

maybe?
