...for values of "WAS" meaning "Is currently", I presume.

It's pretty patently wrong and I think Paul will be gone until after
the 1.6.2 release, so it would be unfortunate to wait. Perhaps we
could program defensively using something like

   if (!is.language(label)) label <- as.character(label)
   txt <- list(label=label, x=x, y=y, gp=gp, ...etc...
