I looked at the source, and created a patch to make it just require the
--server option as the first option.

While I was looking at the code, I noticed that the check_command()
function was busted in that it would accept any abbreviated path of a
command (e.g. "/usr/bin/rs" would match "/usr/bin/rsync").  The author
apparently didn't know that strncmp() stops at a null (unlike memcmp()),
so the length-trimming that is done can just be removed.  My patch fixes
that too.
