[slrn-pre0.9.9] storing raw article via read_article_hook does not work anymore

Hi,

I use, or used to use, roughly the following workaround to have
the current article always available in its undecoded form for
scripts:

#v+
% file tools.sl
implements ("SlrnTools");

static variable current_rawart = "";

static define get_raw ()
{
  current_rawart = raw_article_as_string ();
}
if (1 != register_hook ("read_article_hook", "SlrnTools->get_raw"))
  throw RunTimeError, "failed to register get_raw";
% ...
#v-

Now scripts interpreted after tools.sl have the raw article
available as SlrnTools->current_rawart even *after* a call to
replace_article.

While accessing SlrnTools->current_rawart still works from
/scripts/, it stopped being accessable from read_article_hooks
registered after the hook above.

Is this "cleanup" intentional? Necessary? At least for my needs
it would be nice to have the old behaviour back. At the moment I
can only obtain the raw article from within read_article_hook by
calling raw_article_as_string directly; if the hook the replaces
the article, the raw article has become unavailable for further
processing.
