After my hard drive fried, I lost important configuration settings.
Since then, I haven't been able to use `magit-gh-pulls` without it
incessantly prompting me for my GH username and password. Until I
remember how I previously configured this, I'm disabling it.
Finally ported my up-to-date emacs configuration here. I was putting
this off for a long while, unsure of how to handle all of the work. All
it took was my laptop being fried to force me to do this. So... voila!
