I know the garbage collector trims buffer-undo-list. Does it collect the cons
cell if there are other references to that object (other than buffer-undo-list)?
I tried this:
(setq last1 (last buffer-undo-list))
(garbage-collect)
After the garbage collection, the entry referred by last1 is not in
buffer-undo-list anymore, but still accessible by last1. That seems to support
my theory.
