WIP fix multiline redact bug

[lerouxb]

% rm ~/.mongodb/mongosh/mongosh_repl_history
% npm start

paste in this multi-line command:

printjson(db.createUser(
  {
    foo,
    bar
  }
))

then

% cat ~/.mongodb/mongosh/mongosh_repl_history

Now try it again with the changeHistory line uncommented.

With it commented I get:

% cat ~/.mongodb/mongosh/mongosh_repl_history
printjson(db.createUser( { foo, bar } ))%

With it uncommented:

% cat ~/.mongodb/mongosh/mongosh_repl_history
  }
    bar
    foo,
  {%

I am trying to explain it and none of my theories pan out.
