Not so "diff"-icult after all

I've gone back and updated the way that the filename formatter would work on the command line, and it turns out that on the command line, it's a lot simpler than I'd previously thought.  So here's the ammended version:

perl -e 'print join("\\ ", @ARGV)' [FILE NAME]

I also feel no shame in using yet another "diff" based pun in the title.
