Is there an after-move-functions hook?

Is there an after-move-functions hook?

[Alan Mackenzie]

i.e., something like after-changed-functions, but called each time point
is move?

My answer to the next question is this:  Suppose the user is typing in a
string, and has got this far:

"start of string
                ^
                |
              point

Should he move point away from the string without typing the terminating
", I would like to splash font-lock-warning-font all over the string.  As
soon as point comes back into the string, I would restore it to the
normal restful tasteful font-lock-string-font.

Alternatively, is there any other elisp programming trick which would
achieve this for me?

Have you considered the `point-entered' and `point-left' special text
properties?

Have a look at the pre-command-hook and post-command-hook. Movement of point
is directed by "commands", after all :-)

I did, and rejected them.  After all, point might be getting moved from
one open string (hey, how about that for terminology? :-) and another,
the properties would be the same, so nothing would get called.  Ha!

I've just had another look at the info page.  It was too subtle for me at
first reading.  It looks like _exactly_ what I need.  On each open string
I make point-entered 'restore-this-string-to-polite-fontification and
point-left 'put-horrible-garish-warning-font-on-this-string.

Now I'll just have a quick check that the other Emacs supports this too,
and it's as good as implemented.

Many thanks!
