Ah, makes sense.  I wasn't explicitly aware of VERP before, yet
looking at the header it is pretty obvious what this was about. ;-)

So users need to be careful adjusting their filter rules, as not to
change now and then have to change back again?

Somewhat independent of the current experiment with VERP, I think it
would be great to advise users how to go about filtering e-mails (i.e.,
which headers to filter on and other potential considerations).

Could you send a brief heads-up to gcc@gcc.gnu.org hinting at some
improvements being tested and how to adjust/configure filters that
will work now _and_ in the future?

I volunteer myself to update our list related web page accordingly.

Thanks,
