"syntax propertization" is done lazily, so if/when you need it, you need
to call `syntax-propertize'.  In many cases it's done for you
(e.g. indent-according-to-mode makes sure it's propertized til the end
of the current line), but not in all cases.

Not sure why propertization isn't done for you in the case
of indentation.  Maybe because you sometimes look after the current line?
Or because your indentation doesn't go through indent-according-to-mode?
