[AUCTeX] fill-paragraph and fold mode

[Levon Saldamli]

When M-q (fill-paragraph) is run in a paragraph that contains folded macros
where the contents of the macro is shown (1-argument macro), the displayed
contents is not updated with the new word-wrapped macro content. Example:

general design to a Modelica-specific design using packages, called \emph{The 
Package Design}. Finally, we describe the components of the package in more
detail.

Fill paragraph move "Package Design}..." to next line, but if \emph is folded,
display is not updated until one enters the macro contents with the cursor. 
Also, 
even after update, an extra space is inserted after the newline.
