A few days ago, I wanted to list my branches on a remote. (By "my branches", I mean branches whose head commit I authored.) The first command I tried was: git branch -r --format '%(refname:short) %(authoremail)' \ --list '*aaron@xxxxxxxxxxx*' However, the --list flag only applies filtering using plain refname, not custom-formatted refs. So I just used grep: git branch -r --format '%(refname:short) %(authoremail)' | grep 'aaron@xxxxxxxxxxx' Even though grep works fine, I'd find it convenient for git branch/tag to filter formatted refs when passed both --format and --list flags. I have a patch series implementing this, but before I polish my work to get it submission ready, I wanted to check whether others feel this is a worthwhile change. Feedback welcome.
