    [troff]: Fix Savannah #64937 (del composite char).
    
    * src/roff/troff/input.cpp (map_composite_character): Stop throwing
      diagnostic message when `composite` request invoked with only one
      argument.  This has long worked just fine to delete a composite
      character mapping.  That is something a (rare) user might conceivably
      want to do.
    
    Fixes <https://savannah.gnu.org/bugs/?64937>.
