## Commit Messages
Please strive to write good commit messages. Here's some guidelines to follow:
The first line should be limited to 50 characters and should be a sentence that
completes the thought [When applied, this commit will...] "Implement cmd_move"
or "Fix #742" or "Improve performance of arrange_windows on ARM" or similar.
The subsequent lines should be seperated from the subject line by a single
blank line, and include optional details. In this you can give justification
for the change, [reference Github
issues](https://help.github.com/articles/closing-issues-via-commit-messages/),
or explain some of the subtler details of your patch. This is important because
when someone finds a line of code they don't understand later, they can use the
`git blame` command to find out what the author was thinking when they wrote
it. It's also easier to review your pull requests if they're seperated into
logical commits that have good commit messages and justify themselves in the
extended commit description.
As a good rule of thumb, anything you might put into the pull request
description on Github is probably fair game for going into the extended commit
message as well.
