The quotation marks can be nested, there isn't even a requirement that
they have to come in pairs but they are usually used like this.  With
csquotes there is even a LaTeX package which produces sensible output
from nested quotation marks of the same kind.  For example an input
like «foo «bar» baz» could result in a printed output of «foo ‹bar›
baz» or „foo ‚bar‘ baz“.

Anyway, quotation marks are just an example.  There are many other
places where font locking can go wrong and where I'd like to minimize
the impact of such a failure.

Yes, that's what I had in mind as well.
