[Bug-wget] --no-check-cert does not avoid cert warning

[Karl Berry]

With wget 1.17 (at least),

$ wget -nv --no-check-cert https://www.gnu.org -O /dev/null
WARNING: cannot verify www.gnu.org's certificate, issued by 'CN=Gandi Standard 
SSL CA 2,O=Gandi,L=Paris,ST=Paris,C=FR':
  Unable to locally verify the issuer's authority.

Maybe I'm crazy, but it seems like pointless noise to complain that a
certificate cannot be verified when wget has been explicitly told not to
check it.  Looking at the source, the only way I see to get rid of the
warning is with --silent, which would also eliminate real errors.

I have the sense that at one point the cert warning was not issued in
this case, but I didn't go back and check old versions.

Thanks,
Karl
