As stated in another email, it is still unknown where this "changed"
or if it even "changed" at all in the vanilla sources.
Could you track this down? I still strongly believe this is some
WEB100 change you actually had in your tree, or something like
that.
I don't disagree with your analysis at all. I just want to find out
if it did change in the vanilla sources. Because if it did we can
track down a changelog message and perhaps learn something about what
the code is the way it is.
