Thanks for this. This is the suggestion I ended up taking (modulo taking
'-' as the first argument to 'depacketize').
The 'print $1' part of this makes things a lot nicer, actually, having
removed the " .have" suffix. We can get rid of the expect_haves()
function above, and instead call 'git rev-parse' inline and get the
right results.

Me too :-). Thanks again.
