I agree - whys are very important. I try to document why I do certain things with comments. That said, is there a such thing as a commit message too long? If I were to include the thinking behind code I would have some commit messages over 500 lines long. Currently I just create an Evernote note for each change I make, which documents all the whys, the research, the issues, pros/cons, etc. with a given change. The commit message usually gets a much briefer version of it.
