    src/roff/troff/input.cpp: Delete old comment.
    
    * src/roff/troff/input.cpp (init_registers): Delete comment from 1992.
      C++ maintains separate name spaces for structure tags and type names
      as C does (the main difference being that C++ permits the creation of
      user-defined name spaces which are then partitioned much as C name
      spaces are).  It seems that a version of g++ that was old in 1992
      unified the name space for structure tags and type names.  Support for
      any such compiler would have ceased long ago.
    
    This comment has tripped me up more than once, so I'm getting rid of it.
