That's strange. +repage should be supported from IM 6.1.0 on, AFAIK. 
What gets converted here?

It's definitely not a typo. But if I get it right, it's just a shortcut 
for -page +0+0. (At least for BMP/GIF/PNG output; tested here using IM 
6.4.5, Ubuntu Jaunty build, on PNGs.)

Note that +repage is not (yet?) supported in the GraphicsMagick fork 
(which is the default replacement package at least in Ubuntu), while 
-page is. So to the best of my knowledge, using -page +0+0 is both an 
equivalent and more portable option, anyway.
