testing is an option fo rexisting files, but it's not that user 
friendly; my main point is that pdftex shoul dnot quit on such 
situations and definietly not end up in some funny mode (as it does now) 
and produce an invalid file (in batch mode).

indeed the problem is most prominent with non existing files;

i was thinking about one of those; i dislike the 1 inch, zero dimensions are not always accepted by acrobat (one of those persistent bugs); 1pt is ok for me (i liked the pi -)
