| FWIW this isn't a restriction the graphicsmagick command line tool obeys:
| 
| $ file test.jpg
| test.jpg: JPEG image data, JFIF standard 1.01
| $ gm convert test.jpg test.tif
| $ file test.tif
| test.tif: TIFF image data, little-endian
| $ gm convert test.jpg png:test.tif
| $ file test.tif
| test.tif: PNG image, 640 x 480, 8-bit/color RGB, non-interlaced

Yeah, John Swensen pointed out that this feature is available to the
writeImages function in GraphicsMagick and we've changed to always
prepending the format to the filename before calling writeImages.  So
I think this problem is fixed now.

Thanks,
