    [troff]: Remove workaround for Cfront 1.2 bug.
    
    * src/roff/troff/input.cpp (do_define_macro): Move `dot_symbol` from to
      file to function local scope as originally intended.
    
    "Cfront 4.0 was abandoned in 1993 after a failed attempt to add
    exception support." -- Wikipedia
    
    Surely no one still uses that compiler.
