[troff]: Fix hyphenation problem with kerned letters.

Problem reported by Steve Izma <sizma@golden.net>.

* src/roff/troff/node.cpp
(kern_pair_node::add_discretionary_hyphen): Compute `tf' using the
first node, `n1'.  `n2' might be another kerning node, and the
`get_tfont' member function isn't defined then.
