I'm sorry to report that I've missed a problem in my testing.  The 
commit to fix the interaction between `LaTeX-back-to-indentation' and 
`electric-indent-mode' seems to have broken paragraph filling in 
comments.

To reproduce, use the same setup as the one used in the original report 
(only with the new released version) and visit a file with a long 
comment line. Now call `fill-paragraph' "M-q" with point in this comment 
line.  The line is not filled.  Either reverting to the old definition 
of `LaTeX-back-to-indentation' or disabling `LaTeX-syntactic-comments' 
brings back filling to working conditions.

Best regards,
Gustavo.
