rebase: keep original mq patch format (Issue1574) Rebase now doesn't make assumptions about which format has been used for a mq patch (git or normal). Before finalizing a patch it keeps track of the original format, by reading its header, and then restores the format when reimporting it. This way it also allows for having mixed styles. Note: this version corrects a failure in the test
