I typed a longish reply to this one yesterday, which gmail then
promptly swallowed:-).
Oh well.

The gist of it was "If I get time, I'll look at the code"... and
"interresting that postcat demangles it correctly (so that the postcat
of each queue file is ... well, as close to identical as possible)

Don't have much spare time ATM though, so don't hold your breath:-).
Who knows, Jules might find the time to look at it before the weekend
(when I'll be likely having an hour to spend:-).
