I do. What I meant was I havent (until now) made sure there is a space
after the page number. So to make this work with present version(s) of
dvipng I had to come up with something.

You mean mktexpk and newlines, right? (gs won't get to print anything on
stdout.) So I'm thinking about the possibility of outputting the page
number just before the "depth" text. Problem is, the page number is
output before the initial run is made, the run that calculates the size
of the image. And if a font generation occurs, I really really need that
to know the sizes of the glyphs. I could output "[page" after the
initial run but then I'd lose the nice structure of things needed in the
page being inside the [].

Oh, bugger. What about a simple but perhaps crude way out: a --page
switch, that will make the thing output "page=23414" just before

Downside: things will stop working with earlier versions because this
will be interpreted as -p0 : "start at page 0" and there is no page 0 in
most DVIs, so no output. Bah.

Perhaps I should just output "page=" as soon as --depth or --height is
in effect.
