* descr-text.el (describe-char-eldoc): New function returning
basic Unicode codepoint information (e.g. name) about character
at point. It is meant to be used as a default value of the
and the face `eldoc-highlight-function-argument', if they are to have any
effect.
-This variable is expected to be set buffer-locally by modes that support ElDoc.")
+Major modes should modify this variable using `add-function', for example:
+ (add-function :before-until (local 'eldoc-documentation-function)
+ #'foo-mode-eldoc-function)
+so that the global documentation function (i.e. the default value of the
+variable) is taken into account if the major mode specific function does not
+return any documentation.")
