It seems that you are digging in the wrong direction?  I was worried
about the callers of interpret_branch_name().

But whatever.

I looked at the callers myself while waiting for the test suite to
pass for five integration branches and I think the patch is safe.
There were some silent error returns from the function but your
patch did not touch them (which is good).

I think that is a desired outcome.  Thanks.
