config: Give error message when not changing a multivar
When trying to set a multivar with "git config var value", "git config" issues warning: remote.repoor.push has multiple values leaving the user under the impression that the operation succeeded, unless one checks the return value. Instead, make it warning: remote.repoor.push has multiple values error: cannot overwrite multiple values with a single value Use a regexp, --add or --set-all to change remote.repoor.push. to be clear and helpful. Note: The "warning" is raised through other code paths also so that it needs to remain a warning for these (which do not raise the error). Only the caller can determine how to go on from that.
