    Oops, there shouldn't be "read-only" here, I forgot to refresh
the patch as I'm now seeing... too bad it's too late to resend now.
:-(

Could you send an incremental fix for me to queue up?

Oops, I've rechecked and it should indeed be read-only, so the patch was correct. Sorry. :-)

WBR, Sergei
