That is the case if -a is not used. If -a is used, then you will get a
git confirmation for the cover letter and another for the rest of the
series, which you can say 'a' to and send all of them. This is because
-a uses a different recipients list for the cover-letter than the rest
of the patches.

This also allows for a dry-run by:

yes "n" | send-pull-request ...
