FRC3875 says that if the query does not contain any unecnoded "=" characters, we SHOULD treat the query string as a "search-string", split in on "+" and add every word to the CGI argv. In launch_cgi it's too late because iri->query is the *decoded* query! I have in mind some refactoring around how we decode things, so this is postponed.

Oh my, this is such a stupid mistake. It went undiscovered only because I always used CGI scripts on the first vhost (and hence the offset would be 0) and never on the others.

the executor forks to spawn the cgi scripts, and they inherit the socket for communication with the listener process. Make that impossible.

"test" was replaced by "regress" a while ago

It's how httpd(8) does it, and it allows us to call fnmatch less time
