bug#21594: 25.0.50; (elisp): node `Variable Definitions' is not reachable by `i variable definition'

Yes, thank you.  How about it?

There are several such possibilities.  Both
of those you suggest are fine.

I suggested also `Defining User Options' and
`Defining Customization Variables' (the current
title, inside the node).  (But if we do go with
"option" then the title too should reflect that.)

Nearly anything suggesting defcustom, option
definition, or custom variable definition.

The main thing is to avoid `Variable Definitions',
which invites confusion.

I guess you mean instead of in node `Variable
Definitions', where it's defined now.

That too makes sense, as there we currently
introduce the term "customization items" and
we speak of customizing variables and faces,
without saying that the former are options.
(But the menu refers to user options.)
