OK, so I started reading about this.
I can see that syntax-propertize-rules is a huuuge macro I'm afraid even
to look at from distance;-). Do I get it correctly that it "outputs" a
function, so that I can write
(setq syntax-propertize-function (syntax-propertize-rules (...)))
?

Yes, I know that; I wanted just to experiment a bit to start with.

I have global font lock mode, so font locking is on everywhere.

Now that is strange: it seems that font-lock-keywords-only is set to t
in mu4e-message mode (where I'm now), but grepping through mu4e sources
didn't give any results (nor did isearching message.el). I'll have to
look into this further (check other modes etc.)
