Tested.  Thanks.

Then I have a couple of things to say about this:
* The current behavior is not documented AFAIK [1].
* Even if the behavior was documented, it is not desirable (IMO),
because we already have a specific command to follow a
cross-reference: <RET>.  Thus, if I type <DEL> in an info buffer, I'd
like to see the same behavior (going back) regardless of whether the
point is on a cross-reference or not.  It is much clearer to keep
these behaviors separated.

Of course I agree.  `goto-line' should be consistent with the line
numbers showed in the modeline, regardless of whether the buffer is
narrowed or not.  The current behavior is confusing for users, I
think.


Footnotes:
[1] The info mode help (C-h i ?) says this about <DEL>: "Normally,
scroll backward.  If the beginning of the buffer is already visible,
try to go to the previous menu entry, or up if the is none.".
