@ref without page numbers

[Christopher Dimech]

Although it is useful to have @ref followed by page numbers, page
numbers can make the text very difficult to follow when there there
are two or more references cluttered together, or when the same
reference is used (particularly when this happens on the same page).

Are there ways to stop @ref from showing page numbers?

Although the most important command is @ref, the same thing applies
to other reference commands (@xref, @pref).
