I hadn't considered this issue of case before.  Having to replace all instances of #include <wtf/Foo.h> with #include <WTF/Foo.h> will make this much, much more likely to cause breakages than if we left the original case alone. It also seems somewhat tangential to the goal of moving WTF out of JavaScriptCore.
