Subject: bug#38642: 'C-x RET c' gets stuck in universal-argument loop
Date: Mon, 16 Dec 2019 23:56:08 +0200 [thread overview]
Message-ID: <87a77sgi3r.fsf@mail.linkov.net> (raw)
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.
