in repository groff.

commit 884e9035bc473f215cfd9b9f865fd29e50b0046d
Author: G. Branden Robinson <g.branden.robinson@gmail.com>

    [troff]: Fix `special` request without arguments.
    
    * src/roff/troff/node.cpp (set_special_fonts): Revert part of commit
      44db6efc01, 3 November.  Stop throwing diagnostic and ignoring request
      if given no arguments; that's how you clear the global list of fonts
      designated as special by request (contrast with those that declare
      themselves as special in their description files).
