emacs -Q C-x RET c ;; universal-coding-system-argument RET ;; accept default e.g. utf-8-unix C-u C-b ;; moves backwards 4 chars C-b C-b C-b ... Every C-b still moves backwards 4 chars because it gets stuck with an old 'prefix-arg' in the 'while' loop in 'universal-coding-system-argument'. It gets out of this loop only on an error such as when point reaches the beginning of the buffer that signals an error. PS: this is the simplest reproducible case, but I found this bug by trying to use 'C-x RET c C-u C-u M-x rgrep' that with two C-u prefixes allows editing the grep command.
