Re: [BUG] git config --unset is not idempotent

Arturo Seijas Fernandez [off-list ref] writes:

The command "git config --unset [option]" is not idempotent. It is
currently returning a success  code when the property had already been
set and a 5 error code otherwise.

"rm" is not "idempotent", either.

    echo >file
    rm file ; echo $?
    rm file ; echo $?

The "git config --unset" command signals the inability to unset a
variable when the variable to be unset does not even exist.
