[Groff] General nroff/troff question regarding .bp and .ne in diversions

[Carsten Kunze]

I'd like to use a diversion for printing the bibliography. There I'd like to 
avoid page breaks inside items. I tried to use .ne or .bp, both did not work. 
For .bp I found in the groff that it does not work inside (not-top-level) 
diversions, but for .ne it is not mentioned there.

I wonder why .bp and .ne do not work in diversions. One could say it is an 
inconsistency since "any" other formating request does work. (Of course it is 
correct when it does not work in groff when it did not in traditional *roff.)

Is there any way to force a page break, when I have a multi page diversion? (I 
anyway measure the diversion height, so e.g. including a trimmed .sp should 
work.)
