I think we called it troff, because that's what it was. Brian might remember if it was ever used widely with the prefix. I don't think it was, within 1127. That spelling doesn't appear anywhere in the Research Unix manuals for v8, v9, or v10.

One I've wondered about for a long time is ditroff.
What was that?

1. die-tee-roff
2. dee-eye-tee-roff
3. ditt-roff
4. die-troff
5. Something else...
