Well, Git's own patch revision command line option (-v of git-format-patch)
would put it in the "[PATCH v<N>] Title text" as you had it here, and I'd
presumed that you'd used that command line option. Our practice
here is to manually do "[PATCH] Title text (v<N>)", where the patch version
is postfixed.
