The following bug manifests itself when emacs tries to convert a file
from mbox format to Babyl format.  Here is how to reproduce it:

Send a couple of mail messages, saving the messages in a file using a
header line like

FCC: ~/M/OUTBOX

Then say C-u M-x rmail ~/M/OUTBOX <RET>.  One sees the message about
converting to Babyl format, but then the two messages show up as one
message, concatenated together.

I am 99% sure I understand why this happens.  The problem is in the
functions

mail-do-fcc			(in sendmail.el)
rmail-convert-to-babyl-format	(in rmail.el)
rmail-nuke-pinhead-header	(in rmail.el)

When saving the message, mail-do-fcc creates a header line like this:

   From hanche Wed Sep  9 13:10:44 1992 EDT

but rmail-convert-to-babyl-format uses a regexp to look for the start
of the next message which expects the time zone to be BEFORE the year,
not after - like

   From hanche Wed Sep  9 13:10:44 EDT 1992

I tried correcting it to allow either variant, only to discover that
rmail-nuke-pinhead-header does the same.  And fixing it would be a tad
more complicated, due to the replace-match using the regexp.  Rather
than waste more time trying to correct this, I decided to report the
bug.  I am not quite sure where is the "right" place to correct it -
in mail-do-fcc or the other places.

Also, I would be very surprised if this bug has not already been
reported and corrected, so maybe you have a fix ready?
