These last two lines are due to Debian's groff extension for Japanese.

Yes, we could :-)

Definitely not, see above.

Are you volunteering?  Here the steps:

. Move the common code for gxditview and xtotroff into a library,
  say, src/libs/libxditview.

. Create a new directory src/utils/xtotroff and move the
  corresponding stuff to it.

. Add proper Makefile.sub files, update the top-level Makefiles, and
  remove the Imakefile stuff.  It may be necessary to add some
  autoconf tests to properly handle X11.

You are hitting a weak point of X.  While it is easy to have multiple
locations for binaries, there is just one central directory for
application resources (usually X11/lib/X11/app-defaults) -- no support
for local trees a la TeX's kpathsea, only some environment variables
XAPPLRESDIR in the X(7) man page).  While it is possible (to a certain
degree) to have a local X tree for resources, I doubt that many users
have set up X in this way (and Linux distributions also don't do this

IMHO it makes no sense to have the binary in /usr/local and the
resource in /usr.

Comments welcome, especially who this problem can be solved.
