Delete the redundant "nchild" member of struct roff_node, replacing
most uses by one, a few by two pointer checks, and only one by a
tiny loop - not only making data smaller, but code shorter as well.
This gets rid of an implicit invariant that confused both static
analysis tools and human auditors. No functional change.
