bug#16655: 24.3.50; M-q on a command line does mix up commands and comments

[Sebastien Vauban]

Hello,

With such a shell script file:

--8<---------------cut here---------------start------------->8---
#!/bin/sh

# display symbol definitions, as found in the relevant manual (for AWK, C, Emacs Lisp, and other languages that have documentation in Info)
echo Some text
--8<---------------cut here---------------end--------------->8---

We can observe that:

- `M-q' done on the first line will correctly refill the comment into
  2 lines

--8<---------------cut here---------------start------------->8---
  # display symbol definitions, as found in the relevant manual (for AWK, C,
  # Emacs Lisp, and other languages that have documentation in Info)
  echo Some text
--8<---------------cut here---------------end--------------->8---

- `M-q' done on the second line will completely break the code:

--8<---------------cut here---------------start------------->8---
  # display symbol definitions, as found in the relevant manual (for AWK, C,
  Emacs Lisp, and other languages that have documentation in Info) echo Some text
--8<---------------cut here---------------end--------------->8---

Best regards,

bug#16655: 24.3.50; M-q on a command line does mix up commands and comments

[Marcin Borkowski]

Hi all,

I'm writing to confirm that this is still present in GNU Emacs
25.1.50.1.  To make it a bit more precise: the OP means M-q with point
on either the 3rd line of the script (i.e., the line beginning with "#
display"), which works fine, and then M-q on the fourth line (i.e., the
line beginning with "echo"), which breaks as described below.

Best,
Marcin Borkowski

I can reproduce this on Emacs 26.1 and current master.
