// FEATURE: Missing Host Highlight
//
// In a rule's "Host name ..." condition, exact host names are rendered as a
// link to the host only if the host still exists; an unlinked name means the
// host was deleted. Those names are painted red. Regexes are ignored.
// =========================================================================
