Python, ImageMagick and `subprocess`
I'm trying to assemble images with a call to ImageMagick's `montage` from a Python script like this:

     command = "montage"
     args = "-tile {}x{} -geometry +0+0 \"*.png\" out.png".format( width, height)
     sys.stdout.write( "  {} {}\n".format(command, args) )
     print subprocess.call( [command, args] )

However, montage only shows usage. If I run the command manually, everything works. ImageMagick is supposed to support filename globbing in Windows, so *.png is expanded.
But apparently, this behaviour is suppressed by subprocess.
Do I have to use `glob` to feed `montage` with a list of the filenames?
