git-send-email: allow whitespace in addressee list

When interactively supplying addresses to send an email to with
send-email, whitespace after the separation comma (as in 'list, jc')
wasn't ignored.  This meant that resolving of the alias ' jc' would
fail, sending an email only to list. With this patch, the optional
trailing whitespace is ignored.
