Even if that's not true, it's not a problem: there is simply no other way to
to fix each mode one by one anyway, and every mode that's adjusted is
a step forward.

I'd rather play with syntax-tables to mark them as comments.  Or use
narrowing (together with some convention for how to transfer
parse-state-info from one chunk to another).  The `intangible' property is
just extremely difficult to live with.
