When I was in the Royal Signals we were taught the opposite: better to give
one piece of plaintext away than to make an encryption mistake that could
give away the entire key. (Trivial example: "attack now" gives the enemy 30
seconds warning. "GQ YO" followed by an attack 30 seconds later gives them
four characters of today's Slidex key.)
