My problem is not for a file with an extension. But for a file given
without an extension. Is "\input README" expected to work for a filename
"README", without an extension, or only with the added ".tex" extension?

And from the excerpt given in another message (texmf.cnf), it seems
that it is allowed to even add a ".tex" to a file with already an
extension: "a.b.tex"???!!!
