Doc fix for unsafeInterleaveIO
'unsafeInterleaveIO' allows 'IO' computation to be deferred lazily.
When passed a value of type @IO a@, the 'IO' will only be performed
when the value of the @a@ is demanded. This is used to implement lazy
-file reading, see 'IO.hGetContents'.
+file reading, see 'System.IO.hGetContents'.
