Subject: search branches which contain a blob id
Message-ID: <8a906e45ab8e0252a0be11e4d4e9389e@blinkeye.ch>

To get a list of branches which contain a specific commit we use:

$ git branch --contains <commit id>

Is there a similar way to get a list of branches with respect to a
specific blob (e.g. the actual code change a commit introduces)? 

Obvious use-case: One isn't interested in the commit information (author,
parent, date) but merely in the set of changes a commit introduces.
