Comment 3 for bug 1832922

For 'echo -n x"$IFS"x | od -c' I get:
0000000 x \t \n x
0000005

But based on your comments it seems quite likely I actually invoked it as '/dev/sr0 image.iso'. It is common to treat such things the same whether it's a single '='-separated argument to two separate arguments, and my cursory reading of the code suggested it intended to treat them the same. If the '=' is mandatory it is at certainly worth emphasising that in the docs.

I'm reluctant to do stand-alone experiments for this since I have only a few blank disks, but I'll aim to check this again when I have another image to write.
