RE: Undo limit variables in Emacs Manual

[Drew Adams]

    The variables undo-limit, undo-strong-limit and undo-outer-limit are
    in basic.texi because that's where undo is documented, but they are
    anything but basic.  I think they are important enough to be mentioned
    in the manual.  I'd like to move their documentation to a different
    place in the manual, but I am not sure where.

    Can anyone suggest a good place?

I think they're in the right place. Move them to a subnode of `Undo',
perhaps. Options affecting a feature are usually mentioned along with the
feature.

Otherwise, if you want Basics to just be a Getting Started section, then
cover just a tiny bit on undo in Basics and have the complete doc of undo
elsewhere. In that case, do likewise for all of Basics: treat it as a
Getting Started section in all respects.

In any case, wherever undo is documented completely is where these options
should be documented.
