bug#55040: 29.0.50; Auto-indent-mode and Changelog Messages

[Philip Kaludercic]

When writing change logs in log-edit-mode, I have auto-fill-mode enabled
because 1. I find it convenient and 2. it derives from text mode.  It
has been pointed out to me that this leads to indentation issues, where
a change log entry is interpreted to be an unordered list.  So instead
of

--8<---------------cut here---------------start------------->8---
* lisp/vc/diff-mode.el (diff-add-log-current-defuns): Check
vc-root-dir to prepend the project path to the file being modified.
--8<---------------cut here---------------end--------------->8---

the messages is automatically formatted like

--8<---------------cut here---------------start------------->8---
* lisp/vc/diff-mode.el (diff-add-log-current-defuns): Check
  vc-root-dir to prepend the project path to the file being modified.
--8<---------------cut here---------------end--------------->8---

as soon as the line exceeds the fill column.

Note that manually filling the text using M-q does not run into this
issue.
