looking at netcat

Long story short I was looking to find OpenSSL implementation code in
netcat and didn't find it.  It looks to me like it's libreSSL, but I
could be wrong.  I suspect that if I install the library and mod the
Makefile for nc that the crypto stuff would build, but is there any
interest in using OpenSSL?  It would take me well into the early part
of next year (at least), regardless.

But anyway, that's just a thought.

One thing that I did find in netcat.c is it still has the CRYPTO
options in the call to getopt.  The options don't work, but we don't
get the nice "unknown option" message.

The options to remove are C, c, H, K, R, V, o, T

Here is a patch if you want it.  (`openssl base64 -d` should work to decode it)
