I posted this message about a month ago, but I haven't received 
any replies. I *really* don't want to be the guy that starts 
whining when their question goes unanswered on a public mailing 
list, but this issue happens even with `emacs -Q', so I find it 
hard to imagine that I'm the only one seeing it...

I just realised that I can examine the contents of the overlay 
with `C-u C-x =', and so I did, and I found that indeed, the 
overlay contains an extra "\n". This is for example the overlay on 
"\textit{Aliquam}" in the screenshots I sent:

#("Aliquam\n" 0 7
 (wrap-prefix "" face
              (font-latex-italic-face)
              fontified t))

I also noticed that sometimes, the newline isn't added, though I 
haven't been able to figure out what conditions it. I have, for 
example, an \item in a beamer presentation that shows the problem, 
but when I make the text of the \item shorter, the problem 
disappears. (I confirmed that in the former case, the overlay text 
is "*\n" and in the latter just "*".)

So here's hoping this time around someone may be able to help. 

TIA

Joost
