Another question: what is the purpose of undo-adjusted-mar= kers?

setting the variable without using it.

I found the special= ized GC treatment of undo history markers in
compact_undo_list, so merely having references to the markers via
undo-a= djusted-markers might be a motivation. But I can't think of a
