Subject: [PATCH] Use getSelection in IE where available
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

IE9+ has support for window.getSelection, but we’re still using
document.selection for IE9/10. Only use the old IE selection API if the
modern one is unavailable.
