There are some bugs in the documentation, but all new files are lowercased. They are many times left as is to keep CVS history.
It doesn't look like bugs - see for yourself, it's very systematic, and it works. And PDO has mixed case names too. And so does SPL, SDO, simplexml, domxml and probably a bunch of others. If all these are bugs, which one is not buggy? I am trying to adhere to a standard as much as I can, but I guess I need some standard for that :)
