pullme guesses the wrong branch when requesting a pull of a merge

[ErinCall]

$ git merge origin/master
$ pullme

Do you want to submit a pull request to origin/master? [Yn]

I'm not actually sure how to resolve this, but I'd like to if I can

Maybe skip the first git-log line. I'm pretty sure github would reject pulling HEAD into HEAD anyhow...
