Okay, I spent some time looking at this this morning and I think it's not
actually a regression.

There are two commits involved here. The first, 3173305e, modifies
ITypeComp::Bind to not return an error code if it fails to find the member
being requested. However, a mistake in the patch introduced a problem, where
parent interfaces were no longer being searched when looking for that member.
This was fixed a couple of months later in c0f120db.

Before 3173305e, this sequence would cause Excel to crash. Between 3173305e and
c0f120db, Excel no longer crashes because it's returning a failure code and not
searching parent interfaces. This is "less correct" than the crash. After
c0f120db it's back to the original behavior of searching the parent interfaces
and subsequently crashing.

So, this isn't a regression caused by that commit. Obviously still a bug,
though :)
