Well, it is only an intermediate file, so not sure we want that.
I was wondering more about a behavior where the file would be thrown
away on successful completion but *not* if pdftex fails.  I think we
could have that if the sequence were folded into just one make rule
... is there a good reason for .tex-pdf to be a separate target?
