[Texmacs-dev] In function "edit_dynamic_rep::make_hybrid": why "if (selection_active_small ())"?

[Norbert Nemec]

I often wonder about the behavior of the "\" key that seems to have
changed over the past few versions.

In TeXmacs-1.0.5.11-R2/src/Edit/Modify/edit_dynamic.cpp, I read:

---------------------
void
edit_dynamic_rep::make_hybrid () {
  tree t (HYBRID, "");
  if (selection_active_small ())
    t[0]= selection_get_cut ();
  if (is_func (t, HYBRID, 1) && (t[0] != "") &&
      (!(is_atomic (t[0]) && drd->contains (t[0]->label))))
    t= tree (HYBRID, "", t[0]);
  path p= end (t, path (0));
  if (in_source ()) insert_tree (t, p);
  else insert_tree (tree (INACTIVE, t), path (0, p));
  set_message ("return: activate symbol or macro", "hybrid");
}
-------------------

The first if-query seems to suggest, that it is intended that small
selections are included inside the hybrid while larger selections are
ignored. Effectively that means, that I can easily add markup to single
lines, but not to multiple lines, even though many markup tags (e.g.
<bf|...>) work very well even for multiple paragraphs.

Is the "if (selection_active_small ())" necessary by principle or could
it be relaxed?
