search branches which contain a blob id

search branches which contain a blob id

[Reto Glauser]

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.

Blob == contents of a file. To see what code changed you need to  
compare two blobs (or trees).

git log -S'string to search for'

searches the history for commits which introduced or removed that  
string from a file.

Or 'git log -p', if you want to see the diff alongside the other  
information that log gives you.
