Re: Differences in `ne` and `bp` line-breaking behavior

[Douglas McIlroy]

I don't see this wording as an improvement:

>   .ne d    Advance drawing position to the next vertical
>            position trap and spring the trap, if it is
>            nearer than distance d (default scaling unit v).

The proposal uses nonstandard terminology ("drawing position"),
and is ambiguously worded. It is easy to misread "if" as applying
only to the "spring" clause rather than to the compound of
"advance" and "spring".

Also .ne is effective in the absence of traps, a fact that groff(7)
misses, too.
