From 9e6e3b6be0e9ffe29cf4876ce0b7ded2c3c386b9 Mon Sep 17 00:00:00 2001

Subject: Second step towards parser unification: Replace struct mdoc_node and
 struct man_node by a unified struct roff_node. To be able to use the tok
 member for both mdoc(7) and man(7) without defining all the macros in roff.h,
 sacrifice a tiny bit of type safety and make tok an int rather than an enum.
 Almost mechanical, no functional change. Written on the Eurostar from
 Bruxelles to London on the way to p2k15.
