Bug? Extra whitespace in split subject lines in summary buffer

Bug? Extra whitespace in split subject lines in summary buffer

[Kim F. Storm]

I use Gnus from emacs CVS.

If an article header contains a split subject line like this (where the second
line is indented by a TAB):

Subject: patch: bugfixes in rcirc.el (rcirc-default-user-full-name,
	rcirc-process-list)

the summary buffer replaces the TAB by 3-4 spaces, like this:

    31-May [  84: Daniel Brockman     ] patch: bugfixes in rcirc.el (rcirc-default-user-full-name,   rcirc-process-list)


Is this intentional?  Is there any way to fix it.

I tried setting gnus-simplify-subject-functions, but it has no effect.

I often look at such ones in the nntp groups.  It seems to be
due to the INN server, that replaces LWSPs with a couple of
spaces when generating NOV databases.  I believe it never
happens with the other back ends which generate NOV, such as
nnml.  Though it might sometimes happen between ASCII words and
RFC2047-encoded words.

Maybe yes, in the sense that Gnus assumes that data in NOV have
already been cooked, since the summary lines generation should
be fast anyway.  It will be better that Gnus does nothing with
data in NOV if possible, except for RFC2047-decoding.

There are several ways to do that if you don't mind that it
might slow Gnus.  Here are two examples:

;; 1
(setq gnus-decode-encoded-word-function
      (byte-compile
       (lambda (string)
	 (replace-regexp-in-string
	  "  +" " "
	  (mail-decode-encoded-word-string string)))))

;; 2
(eval-after-load "gnus-sum"
  '(progn
     (setcar
      (cdr (assq ?S gnus-summary-line-format-alist))
      `(replace-regexp-in-string
	"  +" " "
	,(macroexpand '(mail-header-subject gnus-tmp-header))))
     (gnus-update-format-specifications t 'summary)))

It is used for other purposes: to test whether two subjects are
alike, for instance.

This is with groups read from gmane.org -- I don't think it uses INN
anymore.

I see.  Thanks.

This also explains why I didn't notice this problem before...

... it must have started some moons ago, when I switched from
subscribing to the mailing lists to reading the lists on gmane.org.

Thanks.  I'll try those.  

But I also hope that Lars will fix this on gmane.

IMO, the documentation for gnus-simplify-subject-functions
needs clarification.  It just says "... that simpilifes subjects",
but not the circumstances where the simplified subject is used.

Gmane still uses INN.

 $ echo "quit" | nc news.gmane.org nntp | grep 200
 200 news.gmane.org InterNetNews NNRP server INN 2.4.1 ready (posting ok).
