Update of /var/cvs/groff/src/roff/troff
In directory genba:/tmp/cvs-serv20577/src/roff/troff

Modified Files:
        node.cc 
Log Message:
Fix handling of   in grohtml.  To do this, troff emits `N'
with a negative value, representing the width of the unbreakable
space (only for -Thtml).  grohtml then converts this back to
  and uses the value of N as its width.

* src/roff/troff/node.cc (space_char_hmotion_node::tprint,
unbreakable_space_node::tprint): Emit `N-<width>'.
* src/include/printer.h (printer::set_numbered_char): Make it
virtual.
Make members `font_table' and `nfonts' protected instead of private.
* src/devices/grohtml/post-html.cc
(html_printer::set_numbered_char): New member function.
