To reproduce this bug, try to open a file like the attached Org-mode
file.  The phrase "Malformed mode-line" will be echoed in the
mini-buffer even though this file uses legal file local variable syntax.

#+Title: Example Demonstrating a File Local Variable Bug
#+Author: Eric Schulte
#+Date: <2013-03-29 Fri>

This `hack-local-variables-prop-line' function chokes on this variable
name.  To my knowledge it is legal to have a ":" in a variable name,
and this practice is widely used in Org-mode, specifically in
variables which one would want to set in a file local manner.

This patch fixes this bug, I've signed the Emacs FSF copyright
assignment papers, but it is a tiny patch so it shouldn't matter.

Thanks!
