Thanks, but I don't see how this clarifies the issue. Can you tell
more about your motivation?
The motivation is to clarify what a negative NABS means. From the current
document, it is unclear that NABS can be negative.
In that case, the patch is insufficient. First, we don't document
minibuffer-default in the manual, so referencing it will leave the
reader wondering what it is, and how it is set and used. Second, the
doc string of goto-history-element should also explain what is the
meaning of negative values. And third, several functions bind
minibuffer-default to certain values, and I'm not sure this variable
can usefully be documented in a manual.
So I think the text needs not reference minibuffer-default, but
instead talk about "future history", like the Emacs manual does.
