D7649: match: make sure `root` argument is always an absolute path

REVISION SUMMARY
  The `root` argument should already be an absolute path, but we had
  tests that passed a relative path. This patch fixes up the tests and
  adds an assertion.
  
  This assumes that `os.path.isabs('/repo')` will be `True` on all
  platforms we care to run tests on. Augie tested for me that it does
  work on Windows, so that's good enough for me.

     '<something>' - a pattern of the specified default type
 
     Usually a patternmatcher is returned:
-    >>> match(b'foo', b'.', [b're:.*\.c$', b'path:foo/a', b'*.py'])
+    >>> match(b'/repo', b'.', [b're:.*\.c$', b'path:foo/a', b'*.py'])
     <patternmatcher patterns='.*\\.c$|foo/a(?:/|$)|[^/]*\\.py$'>
 
     Combining 'patterns' with 'include' (resp. 'exclude') gives an
     intersectionmatcher (resp. a differencematcher):
-    >>> type(match(b'foo', b'.', [b're:.*\.c$'], include=[b'path:lib']))

-    >>> match(b'foo', b'.', [])
+    >>> match(b'/repo', b'.', [])

     The 'default' argument determines which kind of pattern is assumed if a
     pattern has no prefix:
-    >>> match(b'foo', b'.', [b'.*\.c$'], default=b're')

     The primary use of matchers is to check whether a value (usually a file
     name) matches againset one of the patterns given at initialization. There
     are two ways of doing this check.
