commit 70cd395f3f0b7f7974125ce6e728980e855626ea
Author: Tarek BOCHKATI <tar...@gm...>
Date:   Tue Aug 17 13:29:56 2021 +0100

    server/telnet: support 'CTRL+C'
    
    like in terminal 'CTRL+C':
     - keeps the line content so the user can refer to it (like copy/paste)
     - marks the line with '^C', as hint that the command was not executed
     - permit the user to write a new command
