Subject: bug#23249: 25.1.50; unexpected behavior marking paragraphs in latex-mode
Date: Fri, 08 Apr 2016 21:03:20 -0400

From -Q:

1. open a new buffer foo.tex
2. insert a commented line followed by an uncommented one; e.g.

% dog

cat

3. Put point at beginning of buffer
4. M-h

I would expect the line with "dog" to be marked, but instead, the lines
following are marked.  I see there is some history with the settings of
paragraph-start and paragraph-separate (Bug#5821 and friends), but the
current settings make movement around and uncommenting of commented blocks a
pain.

I can see part of paragraph-{start,separate} in latex-mode are to help
navigating around tex environments and things like that, but it's not
clear to me what further features are packed into the regexen.
