Probably harmless, but it's easy enough to create it; done in r33121.

Changed in r33122 (code) and r33123 (documentation).

I think it's fair to assume that the original motivation for
defaulting to FALSE (compatibility with the GD-based version) is no
longer relevant.

The cairo driver (which will replace the PNG driver at some point)
doesn't even have the option of generating paletted output.
