Yes. There were only very minor editorial changes in the last drafts before
rfc2396bis became RFC 3986.

Ah, OK. I wasn't sure what you meant at first.

I'm not sure without seeing it in action, but this does not look
right to me (the change, as well as its context). I need to look at
what it's doing more closely.

If you need to be lenient, be lenient with the base URI. When you
prepend 'file:' to something, you're making it be absolute, which
probably isn't what you wanted, and probably won't be ideal.
