+ - test_config <config-option> [<value>]
+
+   Set the configuration option <config-option> to <value>, and unset it at the
+   end of the current test. For a similar purpose, test_config_global for
+   global configuration is also available. Note, however, that test_config_*
+   should not be used under a subshell.
+  
+   Example:
+
+	test_config format.coverLetter auto
+
+   Is a concise way to write:
+	test_when_finished "git config --unset format.coverLetter" &&
+	git config format.coverLetter auto
