$ git config --global credential.helper foo
-------------------------------------------
-If there are multiple instances of the `credential.helper` configuration
-variable, each helper will be tried in turn, and may provide a username,
-password, or nothing. Once Git has acquired both a username and a
-password, no more helpers will be tried.
-
-If `credential.helper` is configured to the empty string, this resets
-the helper list to empty (so you may override a helper set by a
-lower-priority config file by configuring the empty-string helper,
-followed by whatever set of helpers you would like).
