Re: fill-paragraph marks buffer as modified even when nothing was done

[Christoph Conrad]

[settings see below]

* emacs -q --no-site-file
* open file
* type very long line
* M-x fill-paragraph <RET>
* Save file => Buffer is not modified
* M-x fill-paragraph <RET>
* Buffer marked as modified, but nothing was really changed.

Why?
