RFC: page numbers to go with `page-delimiter'

[Vaidheeswaran]

I have been tesseracting scanned pdf files -- books really -- for my own 
use.  More specifically I convert it to org-mode -> html export -> 
calibre's ebook-convert -> kindlegen.

The tesseracted file needs to be spell-corrected, unhyphenated etc.  One 
of the practical problems is footnotes.

Most books I have seen number their footnotes in page-local manner. What 
I do as part of post-processing is to "prefix" the page-local or 
chapter-local footnotes with a page number.

Proof-reading takes over a period of few days.  Often I want the page 
nos. of the pdf file to correspond with page number of the ascii file.

Consdiering the above usecase, I wonder whether we can have a canonical 
way to "number" the pages.  Comments welcome.

I can work on a patch if there is some consensus on what can be done.
