Description

There are many git configurations that are preferred to keep in a separate file to avoid committing sensitive information (in a global dotfile as an example). This updates the .config method to accept a file option that allows you to specify the file to save the configuration to (this is equivalent to git config --file some/custom/config name value).

@jcouball from the contributing docs it says to request a review from a maintainer. I'm not entirely sure on the process for doing that (outside of pinging you directly like this). If there is a preference of process I'd be happy to document it 😄 I'm unable to request a review via the typical GitHub UI.

Sorry for the lack of feedback. This project is rather unmaintained at the moment; @jcouball was the last one to review a merge request. James, would you have a chance to give this a look?

Apologies for taking so long to get to this. This addition looks great!

The only thing it is missing is an entry in the README. I'll add this if I don't see a PR in the next day or two.

I'll plan on cutting a new minor-version release within the next week to get this in the gem.
