[PATCH] Add FreeBSD CA bundle location to GnuTLS

[ashish.is@lostca.se (Ashish SHUKLA)]

[-- Attachment #1.1: Type: text/plain, Size: 749 bytes --]

Hi,

I've come across this interesting article[1], and noticed that
`gnutls-trustfiles' is missing the CA certificate path listed for FreeBSD, as
installed by FreeBSD port security/ca_root_nss[2].

So as per the documentation, here is the attached diffs add CA bundle location
for FreeBSD to `lisp/net/gnutls.el', and update the documentation accordingly.

Let me know if there is anything more I can do to make it commit-worthy.

Thanks!
