Hello,

I have stumbled upon gnutls-cli's changed behavior today and could not
find anything in NEWS or Changelog about a policy change. If this
stays in, please document it. (simple patch attached, perhaps the manpage
should say so, too.)

Also I think different default values in gnutls-the-library and
gnutls-cli are confusing. ("My gnutls using app has problem x" -
"Please try to reproduce with gnutls-cli" - "Cannot.") Either
GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT is a more sensible default value
(AFAIK OpenSSL is using it, and about 50% of all TLS certificates are
signed by V1 CAs, e.g.  Go Daddy.) or not. If
GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT is truely evil gnutls-cli should
not use it by default.
