Checking non-active branches

[ChristophWWagner]

Branches that have been committed into can also be out-of-date with respect to origin. If a branch exists at the remote location it would be nice to know if we have unpublished commits resting in any branch that is (i) also known to another remote and (ii) that we have commits of (or are behind that particular origin).

As larger projects tend to accumulate loose ends in form of leftover local branches one could easily forget something there.

I am proposing of reporting the above case by default with pingit status and to optionally extend the scope pingit pull to all available (and matching by-name) branches with an additional flag.

Please comment on this proposal.
