Update of /var/cvs/groff/src/roff/troff
In directory genba:/vol5/tmp/cvs-serv1507/src/roff/troff

Modified Files:
        input.cc 
Log Message:

* src/roff/troff/input.cc (pipe_output): Multiple calls to `pi'
will now form a chain, e.g.

  .pi foo
  .pi bar

is now the same as

  .pi foo | bar

This is for compatibility with plan 9's troff.

* tmac/tty.tmac: Set default tab values to 0.8i to be compatible
with UNIX troff.
* NEWS: Updated.

* doc/groff.texinfo: Add documentation of remaining requests and
registers.
