People would work on individual patches on topic branches that are named
differently from the branch on the other end anyway (the branch that
corresonds to the other end will be used for local integration testing in
such a setup), so I do not see much point in stating which local branch
happened to have been checked out when the patch was generated, in the
output.

Also, in git, there is no independent "branch history", so anybody who
says "this patch was taken from this branch" is either speaking very
loosely, or does not understand git's branching model at all, or bit of
both.

If you have a history of this shape:

                    (other cruft)
                          \
                   ----o---o next
                      /
         o---o---o---o master
        /       /
    ---o---o---A

which "branch label" would you give to the format-patch output that shows
commit A?  It may apply to both master and next, and it is really up to
the project's convention what to do with it.  The side branch the patch
was developed on may be named "quick-hack", which would not have any
relevance to the final location of where that patch wants to be in.
