    doc/groff.texi (Input Line Traps): Fix error.
    
    * doc/groff.texi (Input Line Traps): Fix error; input traps do _not_
      ignore control lines.  Error appears to have crept in with the first
      version of our Texinfo manual, shipped with groff 1.14 (December
      1999).
    
    * man/groff.7.man (Request short reference): Sync with the above; this
      page was correct in groff 1.22.4 but I made it incorrect in c5ff7fd87,
      16 November 2020, thinking the Texinfo manual was right, and
      foolishingly not performing my own experiment.  To efficiently write
      documentation, we must assume that existing documentation lies all the
      time about everything.  (I've found that this practice is even more
      a survival skill for semiconductor manufacturers' data sheets.)
