isPath fails on hashes containing slashes

[velosipedist]

If i try to

// i am on mydomain.com
$.mobile.navigate('#hash') // leads to mydomain.com#hash

it works fine.

But if i try to

// i am on mydomain.com
$.mobile.navigate('#hash/path') // leads to mydomain.com/hash/path instead of mydomain.com#hash/path

i get to subdir instead.

It caused by invalid isPath() check here.

I'm going to send PR in near future if my expectations described above make sense.
