52 * The "current_config_kvi" variable will be non-NULL only when we are feeding
53 * cached config from a configset into a callback.

56 * NULL, then we aren't parsing anything (and depending on the function looking
57 * at the variables, it's either a bug for it to be called in the first place,

59 * fall back to some sane behavior).

68 * found in this variable. It's not part of "cf" because it transcends a single
