Subject: bin/refs: Add option to print revisions
X-Git-Tag: archive/raspbian/2023.7-3+rpi1~1^2~9^2~3^2~2^2~5
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=90dd45fb27594be7fec346987506d08f22a2a37a;p=ostree.git

bin/refs: Add option to print revisions

Allow printing the revision along with the ref. This is very convenient
for looping over the refs in a shell as well as for quickly seeing which
refs are pointed to the same commit.
