Use Test.Regex.PCRE instead of .Posix in compare
This program:
main :: IO ()
main = do re "[^ ]" "\207"
re "[ ]" "\207"
re " " "\207"
re :: String -> String -> IO ()
re r str = let r' = makeRegex r :: Regex
res = matchM r' str :: Maybe (String, String, String, [String])
in print res
prints
Nothing
Nothing
Nothing
for me with Posix, but
Just ("","\207","",[])
Nothing
Nothing
with PCRE. This was causing compare to fail with
Tar line doesn't parse: "drwxrwxr-x simonmar/GHC 0 2012-12-08 21:35 ghc-7.6.1.20121207/libraries/haskeline/tests/dummy-\206\188\206\177\207\\302\\203/"
on the GHC source tarball.
