roman side note

By the way, I've been thinking of roman numerals for the last year thanks to Shannon's THROBAC, so seeing last post's "Ctrl+C-Ctrl+V" made me think of Ctrl+C+(-ctrI)+V. [and thinking so made me tidy towards it, too] Elements out of strictly descending order having their signs reversed by roman convention we can make it just nice looking CCIV.
