Following up on issue 033, the following equation is an
important test of consistent implementations:
resolve_relative_URI(compute_relative_URI(u, base), base) = u

To satisfy this for all examples in section 5.4 of rfc2396bis-02,
a change in the algorithm of section 5.2 is required.
The change is needed to ensure that the ./  and ../ processing 
is applied even when a relative  URI is a path starting with "/".
In my implementation:
                if R_path[0] == "/": T_path = merge('', R_path[1:])

A parser and URI processing algorithms that pass all the tests
are available for examination and comment at the following URL.
The parser is based on abnf2re and the algorithms include
compute_relative_URI as described yesterday, with one bug fix
to handle the authorityless relative URI.  

The test program is available as well.
