 DESCRIPTION
        Return @code{TRUE} if @var{section} is compressed.  Compression
-       header size is returned in @var{compression_header_size_p} and
-       uncompressed size is returned in @var{uncompressed_size_p}.  If
-       compression is unsupported, compression header size is returned
-       with -1 and uncompressed size is returned with 0.
+       header size is returned in @var{compression_header_size_p},
+       uncompressed size is returned in @var{uncompressed_size_p}
+       and the uncompressed data alignement power is returned in
+       @var{uncompressed_align_pow_p}.  If compression is
+       unsupported, compression header size is returned with -1
+       and uncompressed size is returned with 0.
