commit 67528c1f82bed7d6626c3be7a68d3cd98b4944f5

don't add the query to argv

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.
