Syntax error, unrecognized expression when passing string with forward slash ('/') to $

[jordanj77]

$("some-url") returns an empty object.

$("/some/url") throws a Syntax error, unrecognized expression.

Any reason the latter shouldn't just return an empty object?

My reason would be because it's a syntax error and an unrecognized expression.
