--no-to --no-cc also doesnt work (as Id expect), it still wants to cc
to one given in patch-file.

My findings from a quick read of the send-email script:

 * There are --suppress-cc and --suppress-from but there is no
   --suppress-to option at all.

 * There are --no-cc and --no-to but they suppress cc and to
   addresses from the command line (and probably from the
   configuration); addresses a specific patch file lists to be sent
   are not affected.

Documentation updates might be needed.

Indeed.  my brain filled that in.
once I dropped it, the cmd succeeded.

yes, that explains things.

       --no-to, --no-cc, --no-bcc
           Clear any list of To:, Cc:, Bcc: addresses previously set via config.

I did find "config" somewhat ambiguous. "options" would be clearer.

thank you.
