Thanks, and the same with package-vc-prepare-patch, please?

Btw, this kind of reformatting:

> -SUBJECT and REVISIONS are passed on to `vc-prepare-patch', which see.
> -PKG must be a package description.
> -Interactively, prompt for PKG, SUBJECT, and REVISIONS.  However,
> -if the current buffer has marked commit log entries, REVISIONS
> -are the tags of the marked entries, see `log-view-get-marked'."
> +SUBJECT and REVISIONS are passed on to `vc-prepare-patch', which
> +see.  PKG must be a package description.  Interactively, prompt
> +for PKG, SUBJECT, and REVISIONS.  When invoked with a numerical
> +prefix argument, the last N revisions will be used.  When invoked
> +interactively in a Log View buffer with marked revisions, those
> +revisions will be used."

is IMO for the worse: when the sentence starting with "Interactively"
begins a new line, it stands out, which helps users find the most
relevant parts faster.
