This change causes the test to fail on Cygwin.  I think the original "file://" 
is the correct prefix.  If concatenated with "/some/file", it yields the URL 
"file:///some/file".  Your version with "file:///" as the prefix yields 
"file:////some/file", which would refer to a local file "//some/file".

Posix says that the meaning of a path name starting with exactly two slashes is 
implementation-defined.  On Cygwin, it's interpreted as a UNC path name, 
referring to a file on a network.
