While reading this message, I noticed odd behaviour of cursor motion
with <right> and <left> (i.e. right-char and left-char). 

I would expect repeated <right> to move in logical order until the end
of the buffer, but it gets stuck on the newline after "\pstart".
Likewise repeated <left> from the end gets stuck at the newline before
"\pend".

Saving this text in a file "foo.txt" showed the same behaviour (using the
latest emacs-25 branch with "emacs -Q"). Is this expected ?
