All of the above four lines are unwanted in the e-mail body.

 * The first line is a separating line to make format-patch output
   look like a mbox file, and does not even belong to this patch.

 * From: line, when you are not relaying somebody else's patch,
   should not be necessary, as long as you set up your MUA correctly
   so that the e-mail shows a correct From: in its header.

 * Date: is the same; unless you are relaying somebody else's patch,
   in which case you might want to preserve the author timestamp,
   the first time _we_ the recipients see your patch matters more,
   which should be available from the e-mail header.

 * Subject: should be in the e-mail header.  Sometimes when sending
   a patch to an ongoing discussion that has its own subject, it is
   handy to be able to override the title with in-body Subject:, but
   this patch submission is not such a case.  The subjects are the
   same in the fourth line in the body (which should be dropped) and
   in the header anyway in this message, so please edit it out.

In short

 (1) If you cannot convince your mailer to show your @yahoo.com
     address on the e-mail header From: line, then having the
     in-body From: line above (i.e. the second line) is OK as a
     workaround.  We however would prefer if you didn't.

 (2) Edit the other three lines out.

Good find, and nicely explained.  I wonder if we can add a test
or two to t9903-bash-prompt.sh?

The patch itself makes sense.  Thanks.
