    You got it!  Examine the BABYL file and you will see that Rmail 22.3
has added an extra blank line after each of your messages.  That was a
recent (pre transformation to 23) RMAIL bug, I believe.  My older email
does not have these extra blank lines.  I haven't reported all the Rmail
22 bugs I've found because they are moot at this point.

PS, I will send you (Glenn) my relevant test files in case you didn't
keep yours.
