 If the optional argument @var{modulus} is specified, it must be an
-exact positive integer, and the result of @code{string-hash} is
+exact positive integer, and the result of the hash computation is
 restricted to be less than that value.  This is equivalent to calling
 @code{modulo} on the result, but may be faster.
