Message-ID: <83lehcnazb.fsf@gnu.org> (raw)

This part of the changeset looks strange to me:

  diff --git a/lisp/allout.el b/lisp/allout.el
  index be2fd632c69..d3203800168 100644
  --- a/lisp/allout.el

	     (if (yes-or-no-p (format-message
			      "%s entry `%s' is unbound -- remove it? "
			      configvar-name sym))
  -              (delq sym (symbol-value configvar-name)))
  +              (set configvar-name (delq sym (symbol-value configvar-name))))
	   (push (symbol-value sym) got)))

configvar-name is evidently a string, whereas the value returned by
delq is not a string at all.  Do you understand why this code even
calls delq?  If it wants to change the value of configvar-name, it
should assign to (symbol-value configvar-name), no?  And if all it
wants is to skip 'sym' and not add it to 'got', then there's no need
to call delq, right?
