Code review comment for lp:~jeremywootten/slingshot/fix-1213321

It still doesn't fix focus 100% of times on Ubuntu 13.10, I think ibus is still ruining it.

Anyway, a branch got merged in this afternoon that makes it so that the Escape key hides slingshot if the search bar is empty, but clears the search bar if there's text on the search bar.

I branched trunk (lp:slingshot) and the bzr merged this branch and it breaks that new functionality.
