Dr. Matthias St. Pierre fc5ecaddd0 man: harmonize the various formulations in the HISTORY sections
While stereotyped repetitions are frowned upon in literature, they
serve a useful purpose in manual pages, because it is easier for
the user to find certain information if it is always presented in
the same way. For that reason, this commit harmonizes the varying
formulations in the HISTORY section about which functions, flags,
etc. were added in which OpenSSL version.

It also attempts to make the pod files more grep friendly by
avoiding to insert line breaks between the symbol names and the
corresponding version number in which they were introduced
(wherever possible). Some punctuation and typographical errors
were fixed on the way.

=head1 NAME
SSL_SESSION_get0_cipher,
SSL_SESSION_set_cipher
- set and retrieve the SSL cipher associated with a session
=head1 SYNOPSIS
#include <openssl/ssl.h>
const SSL_CIPHER *SSL_SESSION_get0_cipher(const SSL_SESSION *s);
int SSL_SESSION_set_cipher(SSL_SESSION *s, const SSL_CIPHER *cipher);
=head1 DESCRIPTION
SSL_SESSION_get0_cipher() retrieves the cipher that was used by the
connection when the session was created, or NULL if it cannot be determined.
The value returned is a pointer to an object maintained within B<s> and
should not be released.
SSL_SESSION_set_cipher() can be used to set the ciphersuite associated with the
SSL_SESSION B<s> to B<cipher>. For example, this could be used to set up a
session based PSK (see L<SSL_CTX_set_psk_use_session_callback(3)>).
=head1 RETURN VALUES
SSL_SESSION_get0_cipher() returns the SSL_CIPHER associated with the SSL_SESSION
or NULL if it cannot be determined.
SSL_SESSION_set_cipher() returns 1 on success or 0 on failure.
