git/{diff,import}: make it easier to handle manually-asembled patch emails Often, people (including myself) will write emails that can almost be applied with git/import. This changes git/diff and git/import so that things will generally work even when assembling diffs by hand: 1. git/import becomes slightly more lax: ^diff ... ^--- ... will both be detected as the start of a patch. 2. git/diff produces the same format of diff as git/export, starting with paths: --- a/path/to/file +++ b/path/to/file which means that the 'ape/patch -p1' used within git/import will just work. So with this, if you send an email to the mailing list, write up a committable description, and append the output of git/diff to the end of the email, git/import should just work. [this patch was send through the mailing list using the above procedure, and will be committed with git/import to verify that it works as advertised]
