Make sure you have font-lock enabled, open a new .el file and insert:

'(("^[ \t]*\\(?:\\* .*\\)?\\(([^\n)]*,\\s-*\\)$"
   (1 '(face font-lock-warning-face
	     help-echo "Continue function lists with \")\\n(\".") t))

(This snippet comes from log-edit.el)

For me the final "t))" is given font-lock-warning-face.
It also has this text property:

  help-echo            "Hidden behind deeper element; move to another line?"

... which is very useful information!

However, the only way I can see this (other than describe-char) is to
hover over the highlighted text with the mouse.

I think it would be handier if this text were displayed somewhere when
point was in this area.  Some other error-displaying programs, like
flycheck (I didn't look at flymake) will do this already; I just think
it should be standard across Emacs.

Apparently we're supposed to customize help-at-pt-display-when-idle. But 
some modes use the newly added cursor-sensor-functions, forgoing the 
idle timer.
