-credential.helper::
-	Specify an external helper to be called when a username or
-	password credential is needed; the helper may consult external
-	storage to avoid prompting the user for the credentials. Note
-	that multiple helpers may be defined. See linkgit:gitcredentials[7]
-	for details.
-
-credential.useHttpPath::
-	When acquiring credentials, consider the "path" component of an http
-	or https URL to be important. Defaults to false. See
-	linkgit:gitcredentials[7] for more information.
-
-credential.username::
-	If no username is set for a network authentication, use this username
-	by default. See credential.<context>.* below, and
-	linkgit:gitcredentials[7].
-
-credential.<url>.*::
-	Any of the credential.* options above can be applied selectively to
-	some credentials. For example "credential.https://example.com.username"
-	would set the default username only for https connections to
-	example.com. See linkgit:gitcredentials[7] for details on how URLs are
-	matched.
-
-credentialCache.ignoreSIGHUP::
-	Tell git-credential-cache--daemon to ignore SIGHUP, instead of quitting.
