Title: don't mark first comment as error, and rx cleanup

The previous version of `git-commit-summary-regexp' highlighted the
first comment line as a git commit style error. This was because it
did not check if bad non-empty second lines were actually comments.
In addition this commit removes some messy line-start and grouping
constructs which were not necessary.
