Page Numbers in @ref

[Christopher Dimech]

Some have commented that they did not want the page number to be displayed
in some documents (e.g. non-printed pdf output)

For instance, I have used @ref to refer to bibliographic output, where the
page number is not really important - that is, the user can easily find the
bibliographic element, without having to absolutely know the page number.
In other instances, users find the full nomenclature difficult when they have
multiple references (e.g. in tables) and an abbreviated form would be pleasantly
appreciated.  It was pointed out to me that users will mistake abbreviated
versions for a footnote.  However, if the letter 'p' is affixed prior to the
pageno, the ambiguation is solved.

The abbreviated form will be

[Label]\sup{p\pagenumber}

We can have a variable similar to @noindent, where a variable,
e.g. @refpageno can be set to 'full', 'abrv', or 'none'.

'none' will not include  the page number.

It has been suggested that there would be a global variable for
the whole document on how references should be displayed.  But I
claim that users would want the flexibility to switch between
modes in their documents.  For instance, for long documents with
tables and bibliographies, one would want the abbreviated version,
whilst in the bibliographies, one would not want page numbers.
Whereas in the main text, the author would want to use the full
reference description.
