Re: What git config --replace-all ONE_ARG should do?

"Carlos Rica" [off-list ref] writes:

The command 'git config --replace-all ONE_ARG' currently
tries to do the same as the command 'git config NAME VALUE',
using --replace-all as the NAME and ONE_ARG as VALUE,
printing "key does not contain a section: --replace-all".

That sounds silly, and I think it is an improvement to error out in such a
case.
