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.

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.
