[PATCH v3 1/3] t1503: test rev-parse --verify --quiet with deleted reflogs

[David Aguilar]

Ensure that rev-parse --verify --quiet is silent when asked
about deleted reflog entries.

Differences since last time:

This goes back to the original approach of using "git update-ref"
plumbing instead of "git branch" when testing deleted reflogs.

It probably makes more sense to have this at the beginning of a
series as preliminary clean-up.  That way, the more interesting
change does not have to have "test -z $(cat ...)" that makes readers
go "Huh?".

Is this 1/3 (the first one in the series) supposed to pass without
no other patches, either in the series or something outside?

It depends on the patch I sent not too long ago that makes
rev-parse --quiet actually quiet.

I'll rework this series to do the test_must_be_empty cleanup
first and include the prerequisite patch when I re-roll shortly.
