looks good, now tools/tidy and commit --amend -a and push -f :)

The commit message could have a bit more details, e.g. what issue is fixed, why this needs to change, to which versions of which product it applies, link to a bug or a fate entry, the choices you made, etc. Also see http://chris.beams.io/posts/git-commit/ as a helpful guide how to write good commit messages.

What you put into the description of the pull request could also be in the commit message details.

I can recommend the tool "hub" (zypper in rubygem-hub) for easier PR creation. Also, I myself use a script to create a PR with proper description for these simple one-commit PRs:

$ cat $(which git-pr-last )
#!/bin/sh -e
target="${target:-"$USER"}"
git push $target && git show --no-patch --format=%B | hub pull-request -F -
