Due to a bug in dependency_unsatisfied(), tests were executed as long as the first config-line dependency registered didn't match the first directive in the config file.

It "worked" so far, because until recently we only had a single
config-line dependency and only had to check the user-manual
directive, which usually is the first one.

And there I was rewriting client_connection() from scratch,
puzzled that the stupid connection-sharing tests would still
fail.
