Hey,
I've never found any consistency in the capitalization and prefixes
patch titles. I used to capitalize them all but I've seen many
developers use lower case. In any case, I've changed them as you requested.
I've also fixed all my spelling mistakes you've pointed out in the
commit messages.
I'll submit a v4 set next week with these changes and any other feedback
I receive in the mean time.
Thanks,
Logan
