51 * The "cf" variable will be non-NULL only when we are actually parsing a real
52 * config source (file, blob, cmdline, etc).
54 * The "current_config_kvi" variable will be non-NULL only when we are feeding
55 * cached config from a configset into a callback.
57 * They should generally never be non-NULL at the same time. If they are both
58 * NULL, then we aren't parsing anything (and depending on the function looking
59 * at the variables, it's either a bug for it to be called in the first place,
60 * or it's a function which can be reused for non-config purposes, and should
61 * fall back to some sane behavior).

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