bug#8626: 24.0.50; (elisp) Region to Fontify after a Buffer Change - Why a child of Multiline Font Lock?

[Drew Adams]

If you dropped into this node from elsewhere than it parent, you would see
nothing about multiline font-lock constucts.  (And even coming from that node
you will see nothing about them.)

You would learn about refontifying the region after a buffer change, in
particular that in some cases refontifying needs to extend the region.  That's
all.

No one has yet answered the question that would unambiguously tie this to
multiline font-lock constructs: is this region extension for refontifying
pertinent _ONLY_ in the context of multi-line font-lock constructs?  As I said:

> If the _only_ time this is pertinent is in the context of 
> multiline font-lock constructs, then please say so (and
> perhaps why, if helpful).  If it is not the only time, then
> add that this _can_ happen, in particular, in 
> the context of multiline font-lock constructs.

Answer that question for readers and you've fixed this bug.
