It really depends how you get to a new page.  If you have normal text
flow which springs a trap, the \n[.h] register might help.  If you
have .ne requests, the \n[.trunc] and \n[.ne] registers (to be used
within a trap macro) can be useful.  Finally, a .bp call can be
checked with the \n[.pe] register (also within a trap macro).

Note that handling of \n[.trunc] was buggy before version 1.19 of
groff.
