fix make_patchnum.pl branch determination

A previous commit of mine, 9077509c9b9bc1871867a5fba4351b95c670298d,
tried to handle the case where the output of 'git branch' was

    * (no branch)
      blead

to stop it outputting  a 'Use of uninitialized value' warning.
However, my "fix" broke in the case where multiple branches are listed
with the current not the first:

      blead
    * tmp1
      tmp2

Hopefully this fixes it properly.
