Bjarni had previously reported a bug in hypermail's parser
when a mail client misuses the MIME boundary:.

I now found another case, but with a much more popular client:
QUALCOMM Windows Eudora Pro Version 4.0.1
doesn't seem to be adding a last "-" to the boundary string. When trying
to convert a mailbox which had this problem, hypermail stops adding
messages there. It doesn't even add the attachments that were there.
I'll try to add some code for protecting against this problem and for
Bjarni's too. And I think this should make it to 2.0.0 too.
Of course, the problem I'll have is how to recognize that we have anew
message "From someone.xx.xx date" envelope and not a message with
a line giving the same envelope. If you're mbox is IETF-happy (All From
are escaped, it'll work). Otherwise, uh oh. So, I may have to protect
this convertion with an option in case something breaks down...
