This is what was supposed to be an easy two-or-three-line
change to enable a more general-purpose include mechanism
than '@@option'; one that could include an arbitrary file.
This is commit 2 of 2, the "easy" part. Unfortunately, it's
not looking good. The source .md file has UTF8 checkmarks,
and nroff is not happy with those: the generated man pages
are gross.
Another problem: the source .md might need tweaking, because
we don't want a level 1 header in the man page. Obvious solution
is to make kubernetes_support.md a .md.in file as well, and
move the tables to a separate file (or files). Deferred for later.
