Oops, I did it again...

pngcrush does the trick. It's a separately installable package. And it
can be used to ADD chunks too, which seems useful.

Unfortunately it can't delete specific tEXT chunks (i.e., those with
specific keywords). It can just delete all of them, or none of them.
Which is good enough for my immedite purposes, but I guess I am still
looking fo the perfect PNG tool :-)
