Ignoring pdftex primitives (Re: BOUNCE Michael John Downes)

not really a problem as the pdftex support for latex would presumably
just  \let\input\include  and then define \include as now.
That is, it doesn't really matter what you call this as it's real name is
\WhatInputShouldHaveBeen
and so any format is likely to save the old \input for use in dire
emergencies, and then use this new function with the name \input.
So its original name only matters during format making.
