of information (e.g. the place where all patches are spooled) can be
either hard coded or stored in git config entries.

I wanted to keep everything collocated. The time spent setting/unsetting
these variables is completely negligible. I don't mind making this more
streamlined in a v2.

Thanks for the review :)
