Could you give some details?
Functions on font-lock-extend-region-functions should *never* shrink
a region (since that risks inf-looping, obviously). After all, it's
called "...-extend-...", right?
So if font-lock-extend-region-multiline puts beg at 39, it's incorrect
for mhtml--extend-font-lock-region to move it back to 40.
