That depends on what you mean by "effectively".  Let's ignore the
fragment case, because it works differently in RFC2396 and RFC 3986
(though the final result of merging is always the same).

The base URI is file://three/four/a.file, but any use of it to resolve
a relative URI will involve throwing away the "a.file" bit.  The first
step of the resolution algorithm throws away everything after the last
slash in the base URI.  So it has the same effect as if it were
file://three/four/ .
