this patch series introduces a new `--exists` mode to git-show-ref(1) to
explicitly check for the existence of a reference, only.

I agree that show-ref would be the best place for this feature (not
rev-parse, which is already a kitchen sink).  After all, the command
was designed for validating refs in 358ddb62 (Add "git show-ref"
builtin command, 2006-09-15).

Thanks.  Hopefully I can take a look before I go offline.

The series description doesn't say why users would care about this.

If this is just to ease testing, I suggest adding functionality to a
suitable test helper. Anything you add to git-show-ref is a publicly
visible API that needs documentation and comes with a stability
guarantee that is more expensive to maintain than test helper
functionality.
