possible bug default jpg quality or doc error

[Drarakel]

The "-quality" documentation got updated, too (again). So, a re-write is not necessary, I think.
There is still one wrong or misleading sentence now:
http://www.imagemagick.org/script/comma ... hp#quality

For the MNG and PNG image formats, the quality value sets the zlib compression level (quality / 10) and filter-type (quality % 10). Compression levels range from 0 (fastest compression) to 100 (best but slowest).

This second sentence could be deleted. (I already saw users here with commands like "convert input -quality 100 output.png" - wich makes no sense..)
But I won't bug you anymore with this..

Thanks for all your efforts!

The updated "-quality" documentation seems to be perfect now.
Thank you!
