A bad command inside an Edit block written whole is named, not the } after it

A command in a { block that failed to parse ended the block there, so its } was taken as a control message of its own and the write failed unknown control message "}". A { block not yet closed now runs to its } whatever fails to parse in it, and the error names the command (Edit: unknown command z), as the line-by-line path does.
