No, I only think I'm sure. ;-)

After calling `font-lock-fontify-buffer', I can search for zones with face
`font-lock-function-name-face', for example, and I can see that there are no
such zones after some minimal portion of the buffer.

ditto

I believe you, but I'm not seeing `font-lock-default-fontify-region' fontify
everything.  I'm no expert on this at all.  Just going by what I think I see.

Perhaps you're right that if I checked that property throughout the entire
buffer it would be sufficient.  Dunno.  I probably didn't try testing it
everywhere.  But if that's the best test for full-buffer fontification then I
would still prefer something simpler/quicker.

No, no doubt I have.  No doubt I still do. ;-)

I guess so; thanks.  But I would mostly be interested in confirmation that you
are right etc.  I do not see (e.g. by searching for property zones) that the
entire buffer gets fontified by `font-lock-fontify-buffer', but you say it
does/should.
