Well, I thought of that. But I don't think that adding the space makes
a significant difference in repsect to something that would not easily
be valid text. Some people use two hyphens as a dash (with a space
before and after), and this could perhaps manage to get formatted onto
a dedicated line. On the other hand, "--&" or "--#", for example,
would probably be much rarer and easier to identify.

Okay, but there are other problems with requiring that space after the
two dashes. The biggest problem is that it is very easy to not notice
when it is missing. Another problem, just discovered, is that when
someone sends mail in plain text from Hotmail (no one should panic,
it's just an example), then the space gets stripped off and the sig
delimiter no longer works.

Thanks for that clarification.

Okay, we are stuck with just one sig delimiter and it - for reasons
that are still mysterious to me - must have a space after the two
dashes. But what is the harm if TB treats an incorrect sig delimiter
of just two dashes (without the space) as a valid delimiter?
