[PATCH 0/3] t3404 incremental improvements

This set of patches was meant to be a re-roll of [1] addressing Junio's
comments, however [1] graduated to 'next' before I found time to work on
it further, so these are instead incremental patches atop 'next'.

patch 1: address Junio's comment [2]

patch 2: address Junio's comment [3] with a sledge-hammer approach;
whether to accept this patch is a judgment call

patch 3: trivial cleanup which should make the test easier to comprehend
for future readers
