52 * The "current_config_kvi" variable will be non-NULL only when we are feeding
53 * cached config from a configset into a callback.
55 * They should generally never be non-NULL at the same time. If they are both
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,
58 * or it's a function which can be reused for non-config purposes, and should
59 * fall back to some sane behavior).

68 * found in this variable. It's not part of "cf" because it transcends a single
69 * file (i.e., a file included from .git/config is still in "repo" scope).
