I'm sorry, but IMO this change should be reverted, because the
original behavior is consistent with the stand-alone Info reader (and
with my finger memory).

The reason it goes to Functions is because <DEL> from Macros visited 2
nodes: first Functions (it's Prev for Macros, see the header line when
you are in Macros), and then Related Topics.  So typing l goes back to
Functions.  Type one more l and you are in Macros.

Note that "C-h l" does not say "the last node _presented_", it says
"the last node _visited_".

Even if the result is unexpected by someone who is not used to Info, I
think it's Baaad to have Emacs's Info reader behave differently than
the stand-alone reader.

I think it's a bug, because the stand-alone Info reader goes to
Related Topics.
