Re: overriding/removing inherited credential.helper, Do not add an empty value from config credential.helper

Below is current git message when a local config credential.helper has
an empty value. Please skip an empty value.

$ git push --force origin master
git: 'credential-' is not a git command. See 'git --help'.
Did you mean this?
  credential

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?

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

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?
