This is what I wanted to do with the in for-each-ref's pretty
formatting [1]. I used to hack cat-file --batch to extract info I
needed for experimenting with various pack index extensions. If you
are not in hurry, maybe we can introduce something similar to your
syntax, but applicable for all for-each-ref, branch and log family.
Ram, are you still interested in the awesome branch series?
