Why isn't "do not add empty string, or any random string that ends up referring to a helper that you do not have" a solution?

Whatever you do, I do not think introducing a per-variable hack

	[credential]
        	helper = none ;# or "helper = clear"
                helper = mine ;# this is the only thing I use

like that is a sane way to go. "Clear everything you saw so far" would be useful for variables other than "credential.helper"; shouldn't it be done by adding a general syntax to the configuration file format and teach the configuration parser to clear the cumulative definitions so far?
