I think you need to strip any trailing | characters from the strings in the
resulting list before joining with |.

Otherwise, you might build one||two||three
Which clearly isn't what is wanted.

Hmmm...I guess I mean "up to one trailing | character"...in case someone
really wanted one||two for some really strange reason.

I agree.

When we first installed a Mailman version with topic support, I messed
around with it, and it didn't work.  Since I didn't care much, I ignored the
problem rather than figuring out what I was doing wrong.  (This thread has
made that obvious, of course.)
