hmmm one more thing,

i dun really understand

$scope.$target = $attrs.href || '_self';

am i missing something?
why do we set target to the value of href?

[perrygovier]

Hey Roychoo, good catch. That was added as part of an earlier PR and we completely missed that. Would you like to change $attrs.href to $attrs.target?

@ajoslin Any reason not to add this?

[roychoo]

@perrygovier sure. will add this later. :)

That's why unit tests rock! Fixed.
