Branches field in commit detail is questionable
When looking at the commit detail for a git repository, such as this one there is a field on the right-hand side labeled "Branches" that seems to be wrong, or at least, unclear. For this particular commit I've linked to (i.e., 4fe9d15), it shows "master" as the branch. But that commit has two different branches as descendants: "master" and "side"; both of these tips can be seen as descending from this commit in this overview. Perhaps this branches field is intended to indicate which branch the project was on when the commit was made, but to the best of my knowledge this can't be done; this info is only available in the reflog, which isn't pushed.
Is this a bug and "branches" should show all descendant branches (which it doesn't), or a poorly documented feature? If the latter, what is this field showing?
