Maybe instead of using font-lock to hide long parts

directly in compilation-filter/grep-filter?
I now have a rough patch that does this, but the problem is that even if
I splat a "..." display over the text, font-lock seems to insist on
going over the data anyway, so the display is still dog slow.
I thought I remembered there was a way to say to font-lock "ignore this
bit of the buffer", but I can't find it now. Do I misremember?
