D'0h ok.. but the scheme would work with any generated msgid, all we need is to generate one for commits that lack a Link tag and insert it using the prepare-commit-msg/commit-msg hooks and for the post-commit hook to recognize it and use that actual msgid. The only thing to avoid is msgid collision, but given that MUAs already have this problem all we need to do is borrow some of their logic. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
