I do mention a good deal of this in the blurb in part [0/2] of the patch,
though I don't cover the readpage/readpages() debate. Ideally readpage()
should do just that, read a page, based on the size of the page passed,
and not assume "page" means "PAGESIZE."

I can also make the "help" text for the option more descriptive if
desired.

Thanks for your comments!
