Beat Bolli e9b7724687 doc/man3: reformat the function prototypes in the synopses
I tried hard to keep the lines at 80 characters or less, but in a few
cases I had to punt and just indented the subsequent lines by 4 spaces.

A few well-placed typedefs for callback functions would really help, but
these would be part of the API, so that's probably for later.

I also took the liberty of inserting empty lines in overlong blocks to
provide some visual space.

=head1 NAME
RSA_sign_ASN1_OCTET_STRING, RSA_verify_ASN1_OCTET_STRING - RSA signatures
=head1 SYNOPSIS
#include <openssl/rsa.h>
int RSA_sign_ASN1_OCTET_STRING(int dummy, unsigned char *m,
unsigned int m_len, unsigned char *sigret,
unsigned int *siglen, RSA *rsa);
int RSA_verify_ASN1_OCTET_STRING(int dummy, unsigned char *m,
unsigned int m_len, unsigned char *sigbuf,
unsigned int siglen, RSA *rsa);
=head1 DESCRIPTION
RSA_sign_ASN1_OCTET_STRING() signs the octet string B<m> of size
B<m_len> using the private key B<rsa> represented in DER using PKCS #1
padding. It stores the signature in B<sigret> and the signature size
in B<siglen>. B<sigret> must point to B<RSA_size(rsa)> bytes of
memory.
B<dummy> is ignored.
The random number generator must be seeded prior to calling RSA_sign_ASN1_OCTET_STRING().
RSA_verify_ASN1_OCTET_STRING() verifies that the signature B<sigbuf>
of size B<siglen> is the DER representation of a given octet string
B<m> of size B<m_len>. B<dummy> is ignored. B<rsa> is the signer's
public key.
=head1 RETURN VALUES
RSA_sign_ASN1_OCTET_STRING() returns 1 on success, 0 otherwise.
RSA_verify_ASN1_OCTET_STRING() returns 1 on successful verification, 0
otherwise.
The error codes can be obtained by L<ERR_get_error(3)>.
=head1 BUGS
These functions serve no recognizable purpose.
