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.
