Extracts variables out of a loop

[pbu88]

Small performance improvement.

Also, I'm thinking it would be nice to support unified diffs (not only git diffs). That's what took me to this intermediate step (trying to refactor a little bit). Support for unified diffs is almost there, but some minor headers adaptations needs to be done.

This is very useful for sysadmins for example. A lot of time they are changing .conf files and I've found is better for them to read unified diffs than just telling them which line to add/change.

Hope this helps!

LGTM 👍

Thanks

@pbu88 Looking forward for the unified diff support.
If you need any help with the code just tell me.
I am not much experienced with JS and Node, so good practices might be missing in some occasions. Feel free to warn me about any improvements I can do in the lib.

Same here about Node :)

It shouldn't be hard. I was thinking about refactoring the logic for parsing git diff into its own method, then write another for unified diffs (which will use a lot of logic from the one already in git diff, only the headers are sort of different). Thanks for the support, I'll give it a try when I have some time!
