There is more to consider:  Kpathsea searches each texmf tree for a
file without an extension and if none is found it appends '.tex' to
the name and searches again within the same tree.

It does *not* search all trees for a file without extension and
restart the search again if none is found.

This is intended behavior.  So people who need files without
extensions should keep this in mind and be very careful.
