Documentation
Whether lisp-fill-paragraph should fill strings as Elisp doc strings.
The default behavior of lisp-fill-paragraph is tuned for filling Emacs
Lisp doc strings, with their special treatment for the first line.
Specifically, strings are filled in a narrowed context to avoid filling
surrounding code, which means any leading indent is disregarded, which
can cause the filled string to extend passed the configured
fill-column variable value. If you would rather fill the string in
its original context, disregarding the special conventions of Elisp doc
strings, and want to ensure the fill-column value is more strictly
respected, set this variable to nil. Doing so makes
lisp-fill-paragraph behave as it used to in Emacs 27 and prior
versions.
