Re: [AUCTeX-devel] paragraph-start in modes other than latex

[Ikumi Keita]

Hi Marcin and Arash,

Thank you very much for your replies!  Taking into account the two's
comments, I suppose that a reasonable change for plain-tex.el would be
to remove anchor "^", to leave bunch of macros, not to add "\b" and
remove "\[" and "\]".

If this is appropriate, `paragraph-separate' of plain-tex.el needs no
modification.

Regarding texinfo, I realized that
>> ----------------------------------------------------------------------
>> (set (make-local-variable 'paragraph-start)
>> (concat "\b\\|address@hidden \n]\\|" paragraph-start))
>> ----------------------------------------------------------------------
is just copied from Emacs' standard texinfo.el and almost the same
except the anchor "^".

Here is my tentative proposal:
