bug#21645: Inquiry: reproducibility of a paragraph-fill bug

[gojjoe]

Hi all,

I noticed that both fill-paragraph and LaTeX-fill-paragraph, 
called on a paragraph that contains "\( ... \)" inline math, 
will break lines after each "\)", except those on the last 
line. For example ("*" indicates where lines break, in case 
formatting is lost via email);

blah blah blah \(blah\)*
blah \(blah\)*
blah blah blah blah blah blah blah blah blah blah blah blah 
blah blah*
blah blah \(blah\)*
blah blah blah blah blah blah blah blah blah blah blah blah 
blah blah*
blah blah blah blah \(blah\) blah \(blah\) blah.

Weird behaviour, it appears also launching Emacs with the 
--no-init-file option.

Can you reproduce this? If so, is this to be considered a 
bug of fill.el or auctex?

Cheers,
J
