+"urlapi: have *set(PATH) prepend a slash if one is missing".
+
+All that test code had been added with b03e070420606d407df2ec5e9dfa7043ecc46177
+"ucb: webdav-curl: fix CurlUri::CloneWithRelativeRefPathAbsolute()", and it
+looks harmless for our use cases that cURL started to behave differently there
+now.  So instead of accepting either of the outcomes depending on what cURL
+version is being used, just change the test code to not leave out the
+path-absolute in the calls to CloneWithRelativeRefPathAbsolute (which is
+documented in ucb/source/ucp/webdav-curl/CurlUri.hxx to take
+
+>     /// @param matches: relative-ref = path-absolute [ "?" query ] [ "#" fragment ]
+
+and path-absolute cannot be empty as per RFC 3986 "Uniform Resource Identifier
+(URI): Generic Syntax").
