Yes, sort of. It's used to be because we "don't know" the length of
the "%1$s" strings (i.e., the PROGRAM_NAME macro, which here is just
"mtdinfo"). I suppose we could either hardcode the spaces in or try to
do some sort of "ARRAY_SIZE" trickery (as found in the Linux kernel)
to find the length of PROGRAM_NAME. I'll see how the second option
works (for a potential v4 patch?) unless someone objects.

Still a valid question...in fact, this was something I had meant to
reconsider before sending this patch, but I forgot :)
