We should really advise (new) developers to send rebased patches
that apply cleanly and use git-send-email rather than all other
obscure ways.

+patch set. One should avoid sending patches as attachments, but rather send
+them in email body among with commit message. If a developer is sending
+another version of the patch (e.g. to address review comments), he is advised
+to note differences to previous versions after the "---" line in the patch so
+that it helps reviewers but doesn't become part of git history. Moreover, such
