Description:
------------
Trying to load a private key with openssl_get_publickey yields an error when it in 
fact shouldn't.

Test script:
---------------
<?php
openssl_get_publickey('-----BEGIN RSA PRIVATE KEY-----

-----END RSA PRIVATE KEY-----');
echo openssl_error_string();

Expected result:
----------------
I wouldn't expect there to be any output.

Actual result:
--------------
"error:0906D06C:PEM routines:PEM_read_bio:no start line" is the output.

I forgot to say...  this is an issue because the documentation implies that 
private keys work:

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
