This patch looks unsafe, and in the examples listed in the patch
description the changed behavior does not look like an improvement.
Worse, the description lists a few examples but gives no convincing
explanation to reassure about the lack of bad behavior for examples
not listed.
Perhaps this patch has a prerequisite and has come out of order.
Hope that helps,
