That's what I do.  (See `font-latex-fontify-region'.)  But the
multiline construct does not get fully highlighted if I don't set
j-l-c-u-p or set the fontified property to nil.

In AUCTeX's LaTeX mode ``text in quotes'' will get highlighted.  If I
start a quote, move a page downwards and insert the ending quotation
marks, only part of the text in quotes will get the appropriate face
if j-l-c-u-p is not set.

I'll try to come up with a testcase demontrating this in a
programmatic way on Friday.
