Oh, I'm sure I made many mistakes.  ;)

That's probably the best option, since it should allow users to take
advantage of setting X-extent for other barline styles.

                  extract_grob_set (h, "elements", helts);
                  for (vsize k = helts.size (); k--;)
-                   if ("" != robust_scm2string (helts[k]->get_property 
("glyph-name"), ""))
+                   // Only non-empty bar lines count.
+                   if (h->extent (h, X_AXIS).length () > 0)
                      return false;

If you're checking the extent of the BreakAlignGroup itself instead of
its cause (the BarLine), can't you get rid of the grob set `helts'
here?
