mail.sh: always include "References" header

Although it makes the most sense to include a "References"
header for branch updates, tags can also be updated multiple
times.

In fact, anything that gets updated really should have
the header for grouping purposes.

Therefore include the header whenever the refname is set.

Also squeak in a tiny "|| :" cleanup at the same time.
