narrowmatcher: propagate the rel() method

The full path is propagated to the original match object since this is often
used directly for printing a file name to the user.  This is cleaner than
requiring each caller to join the prefix with the file name prior to calling it,
and will lead to not having to pass the prefix around separately.  It is also
consistent with the bad() and abs() methods in terms of the required input.  The
uipath() method now inherits this path building property.

There is no visible change in path style for rel() because it ultimately calls
util.pathto(), which returns an os.sep based path.  (The previous os.path.join()
was violating the documented usage of util.pathto(), that its third parameter be
'/' separated.)  The doctest needed to be normalized to '/' separators to avoid
test differences on Windows, now that a full path is returned for a short
filename.

The test changes are to drop globs that are no longer necessary when printing an
absolute file in a subrepo, as returned from match.uipath().  Previously when
os.path.join() was used to add the prefix, the absolute path to a file in a
subrepo was printed with a mix of '/' and '\'.  The absolute path for a file not
in a subrepo, as returned from match.uipath(), is still purely '/' based.
