Problem Description

In some situations, the output of some commands breaks syntax highlighting.

Steps to Reproduce

Create an index on a big collection and run

db.currentOp({
'msg' :

{ $exists: true }

,
'command':

{ $exists: true }

,
$or: [
{ 'command.createIndexes':

{ $exists: true }

},
{ 'command.reIndex':

{ $exists: true }

}
]
}).inprog.forEach(function(op)

{ print(op); }

);

Note that one of the fields contains a Buffer.

Expected Results

Syntax highlighting works well

Actual Results

After the Buffer all the text is white.
