openssl/util/find-doc-nits
Rich Salz 65718c516e Document most missing options
Add cmd-nits make target.

Listing options should stop when it hits the "parameters" separator.

Add missing .pod.in files to doc/man1/build.info

Tweak find-doc-nits to try openssl-XXX before XXX for POD files and
change an error messavge to be more useful.

Fix the following pages: ca, cms, crl, dgst, enc,
engine, errstr, gendsa, genrsa, list, ocsp, passwd, pkcs7, pkcs12, rand,
rehash, req, rsautil, s_server, speed, s_time,
sess_id, smime, srp, ts, x509.
