Internally mutating the option argument causes unexpected behaviour.
Internally mutating the option argument causes unexpected behaviour.

Example:

    var options = {regexp: true};
    JSHINT("/*jshint regexp: false */\nvar c = /a.b/;", options);
    JSHINT("var a = /d.e/;", options);

In the second call, `options.regexp == false`, and no errors are logged.
