As far as I can tell, changing the default paper size currently requires
editing either groff font configuration or (if it's set up that way) a system
configuration file such as /etc/papersize.  Systems that use libpaper allow
some more flexible approaches: you can use the LC_PAPER environment variable
to use a default paper size based on the locale, or the PAPERSIZE environment
variable to set it directly.  Would it make sense for groff to have optional
support for libpaper?  Looking at paper.h, its API doesn't seem outrageously
complex.

Of course, one can always use something like `-P-pa4`, so this isn't strictly
required, but it would allow somewhat better integration with systems that
support libpaper: groff would then use the same approach for selecting the
default output paper size as other programs.
