I'm sure if there is a hell, mine will involve fixing errors in troff documents. Maybe with some m4 for added spice.
Anyway a line with zero width break points using \: can't be adjusted, but a ".ad l" and ".ad" before and after the offending line fixes it and looks ok.
Hell is actually just an old version of Heaven but people are kept there to refactor legacy code.
(and of course, updating gibberish documentation files)
