That's a question for the configuration parser, right?  I don't have an
informed opinion on how it should be implemented, and am OK with any
syntax to clear a variable.

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?

I would like that too (needed it today).  Maybe the empty string (as
suggested) or "none" could be acceptable.

"none" seems friendlier and is very unlikely to collide with an actual
credential helper.
