Fix global fallback when host-specific setting is undefined

Browse source 
This commit only changes behavior if the hostname is a falsy string
(`''` or `'0'`) and there is a variable that:
  * was not set globally before the host definition,
  * was not set in the host definition,
  * was set globally after the host definition, and
  * is relevant to the host.
