Border color for input group on focus highlighted unevenly on right

[jplehmann]

I'm having the same problem which can be seen in BS documentation:
http://getbootstrap.com/components/#input-groups-buttons

Click on the right example "Search for...". Notice how the blue border/outline on the right side is covered up. The left example doesn't really have this problem.

The blue comes from .form-control:focus { border-color, outline, webkit-box-shadow, box-shadow } at least on my page.

My site is: http://www.morphmarket.com and you'll see the same issue on its search input and the middle button too. I messed with Chrome inspector for a while, but this is beyond me -- and when I saw the docs had the same problem, I figured I could create an issue. Thanks!

PR submitted @jplehmann — thanks for reporting this. @mdo build failed due to a travis issue it seems not the code change itself. JSBin of the fix is in the PR. Just a simple z-index change.
