Use a cover letter by default for pull requests
Use a cover letter by default for pull requests

Pull requests should normally include a cover letter with a
justification.  Currently --pull-request suppresses interactive cover
letter editing and includes a default one that just says "Pull request".

This patch enables cover letter editing by default and also allows this
to be overridden via gitpublishprofile.<profile>.message or by a
previous --edit invocation.
