Subject: [PATCH 1/2] roffit: strip italic corrections

The `\/` escape sequence inserts an italic correction, i.e. a small piece of
horizontal motion (1/12 em) that should be sufficient to separate an italic
character from a following roman character. Similarly, `\,`, adds a left
italic correction, always a zero motion, that should be sufficient to separate
a roman character from an immediately following italic character.

roffit now simply removes them
