I've changed that to use a conditional block, like we use for all other
conditional options.

I was wodnering whether we would have to do something about that, but
no. It's disabling the option, and the configure script checks it only
if vhost-user is set.
However, there's also vhost-user-fs that we do not handle. The default
is disabled, so that's still OK...
Applied to master, thanks.

Yann E. MORIN.
