bug#7469: 24.0.50; report-emacs-bug is broken again (on Windows)

["Drew Adams" <drew.adams@oracle.com>]

Regression.
(More or less the same problem we had a few months back, bug #5299.)

Cannot send a bug report on Windows.  Symptoms slightly different, however.

When I hit C-c C-c in the bug-report window and answer `yes' to the prompt to
send the report, it simply claims that it sent the bug report (but it did not),
and shows me the buffer *sent mail to bug-gnu-emacs@gnu.org*.

It should invoke my mail client (Outlook), popping up a new mail message
addressed properly with the Subject filled out and the body having text saying
that you can paste the bug-report contents there.

The `From' field in the buffer *sent mail...* shows this:

From: dradams@DRADAMS-LAP1.i-did-not-set--mail-host-address--so-tickle-me

Users should not need to set anything in order to be able to send Emacs bug
reports.  It is not the users who need "tickling" here.

First reported to emacs-devel (no response) for this version:
