* tmac/groff_ms.man: Typographical improvements.

* doc/groff.texinfo: Updated version and copyright.
* src/devices/grops/grops.man: Updated.

* tmac/groff_tmac.man: Fix `ig' macro.

* tmac/an-old.tmac (ne): Redefine `ne' request to be a no-op in
nroff mode.
Use `.ne' unconditionally everywhere.
(TS): Only insert some vertical space.  Doing a page break is no
longer necessary due to the redefinition of the `ne' request.

* src/libs/libdriver/input.cc (parse_D_command): Don't emit a
warning for unknown subcommands but parse and pass them to the
device driver.
