send-pull-request: streamline git-send-email usage

The script was sending one patch at a time, which defeats the internal
confirmation mechanism of git-send-email (which would otherwise allow
the user to send all patches or abort immediately).

Rework the sending logic to use no more than two commands. Use two
commands when the cover letter is to be sent to all recipients with
the -a argument. Otherwise, send all patches via the same command.

The script duplicates git's send confirmation, eliminate that.
