The bug is caused by a regexp for detecting code comments in
`LaTeX-fill-region-as-paragraph' failing on "\ %".  The respective
function call is something like
(re-search-forward "[^ \t\r\n%\\]\\([ \t]\\|\\\\\\\\\\)*%" nil t)

I'd propose to change this to
(re-search-forward "[^\r\n%\\]\\([ \t]\\|\\\\\\\\\\)*%" nil t)
unless someone can come up with a false positive or negative for this
regexp when detecting code comments.
