{- These (78-81) are some awkward test cases thrown up by a question on the URI list:
     http://lists.w3.org/Archives/Public/uri/2005Jul/0013
   Note that RFC 3986 discards path segments after the final '/' only when merging two
   paths - otherwise the final segment in the base URI is maintained.  This leads to
   difficulty in constructing a reversible relativeTo/relativeFrom pair of functions.
