Check other branches #4
Description
Some useful commits might exist in a non-default branch that had been copied during forking or later created by the forker. So it seems ideal to check other branches after checking the default branch.
After finding an branch that is ahead of the root repo, the script can skip other branches and move on to the next fork for the sake of speed. It could print "10+ commits ahead" or "At least one branch is 10 commits ahead" instead of "10 commits ahead".
Or maybe there's a way to check all branches at once.
