    Decompresses the data in *string*, returning a string containing the

    The absolute value of *wbits* is the base two logarithm of the size of the
    history buffer (the "window size") used when compressing data.  Its absolute
    value should be between 8 and 15 for the most recent versions of the zlib
    library, larger values resulting in better compression at the expense of greater
-   memory usage.  The default value is 15.  When *wbits* is negative, the standard

+   than the size originally used to compress the stream; using a too-small
+   value will result in an exception. The default value is therefore the
+   highest value, 15.  When *wbits* is negative, the standard
    :program:`gzip` header is suppressed; this is an undocumented feature of the
    zlib library, used for compatibility with :program:`unzip`'s compression file
    format.
