bug: emphasization not performed at end-of-line

bug: emphasization not performed at end-of-line

[Karl Kleinpaste]

The difference between these two lines...
*test*
*test* here
...is that the former has emphasization at line's end, and the latter
does not.  Emphasization of the former does not occur, but it does occur
for the latter.  It seems to me that this worked long ago, but has not
worked properly for a long time -- I can't even guess when it stopped
working, but it was probably over a year ago.

This is driven by gnus-emphasize-whitespace-regexp (defvar'd in
gnus-art.el) and gnus-put-overlay-excluding-newlines and
gnus-put-text-property-excluding-newlines (defun'd in gnus-util.el).
Any ideas for what has gone wrong with this?

It works for me: "*test*" in both lines are emphasized (bold) when I
read your article: http://koldfront.dk/misc/gnus-emph.png

I am using No Gnus (from cvs, updated 5 minutes ago) in XEmacs 21.4
(patch 22) "Instant Classic".

Did you change your configuration then, or could it be an XEmacs
21.5-thing?


  Best regards,

Very interesting.  I am using...
- No Gnus v0.11, "cvs up" as of a few minutes ago, without any
customization of (e.g.) gnus-emphasize-whitespace-regexp
...and...
- XEmacs 21.5 (beta28) "fuki" [Lucid] (i386-redhat-linux, Mule) of Sun Mar  8 2009 on x86-5.fedora.phx.redhat.com
  (...as provided in Fedora11.)

Since it works for you, it would seem that this is an XEmacs glitch.
Not good.

The problem is due to the difference of the character syntax of
the newline character between XEmacs 21.5 and the others.

This form

(char-syntax ?\n text-mode-syntax-table)

returns `?\.' in XEmacs 21.5 whereas `? ' in XEmacs 21.4 and
FSFmacs.  I don't know why.

Try adding the following snippet to your ~/.gnus.el file:

(eval-after-load "gnus-art"
  '(modify-syntax-entry ?\n " " gnus-article-mode-syntax-table))

`gnus-article-mode-syntax-table' is a syntax table that is made
from `text-mode-syntax-table'.

Thank you very much, that fixed it.

Thanks for isolating it to this issue.  That helped a lot.  This has
now been fixed in the Mercurial repo for XEmacs.  (And thanks to Karl
for reporting the issue in the first place.)

cheers,
