Log Message:
* src/roff/troff/node.h (unbreakable_space_node, hmotion_node,
space_char_hmotion_node, overstrike_node): Add `get_hyphen_list()'
and `add_self()' methods to avoid hyphenation.  For example, the
hyphen list for `foo00bar' was `foobar', causing insertion of a
soft hyphen after `foo'.  Now the hyphen list is correctly
`foo<ignore><ignore>bar'.
