 {{{js_escape('\n')}}} gives only {{{n}}} and it should give {{{\n}}}
 instead.

 The problem is that first {{{stripslashes}}} and then {{{addslashes}}} are
 applied to the string, which doesn't guarantee that the string will remain
 the same.

 Also, I still don't get why {{{js_escape}}} has to do something more than
 replacing {{{'}}} with {{{\'}}}, {{{"}}} with {{{\"}}} and  newline
 characters with {{{\n}}}.  Isn't its only purpose to make sure that the
 given php string is processed without errors by javascript? Why do we use
 {{{wp_specialchars}}}? Why do we put html entities, when we aren't sure
 the javascript code expects those?
