BN_MONT_CTX_set() sets up the B<mont> structure from the modulus B<m>
by precomputing its inverse and a value R.
-BN_MONT_CTX_copy() copies the B<N_MONT_CTX> B<from> to B<to>.
+BN_MONT_CTX_copy() copies the B<BN_MONT_CTX> B<from> to B<to>.
BN_MONT_CTX_free() frees the components of the B<BN_MONT_CTX>, and, if
it was created by BN_MONT_CTX_new(), also the structure itself.
