This reverts commit 99d8d3c21f2bcdcc15390964e893f0de5221ef18. We need to revert the CodeMirror upgrade to 5.11 which was done by Id02e65 because it broke displaying the file diff for certain files as reported by issue 3927 [1]. Since this commit relies on the new CodeMirror version is must be reverted as well. [1] https://code.google.com/p/gerrit/issues/detail?id=3927 Change-Id: I6b15aa239666348e5c4ac50f4b248ef9a8f00cc5
