In his latest diffs, Karl writes:

! No single format-independent path specification, such as

Ugh.  I'd still prefer some language encouraging people to gravitate towards
saying \input latex/foobar, etc.

But also, I think that the issue of when duplicate file names within
texmf/tex are allowed should be explicitly addressed.  Current practice seems
to be:

    1.	names of TeX input files must be unique within any of the first-level
	subdirectories of texmf/tex, and
    2.	names of image input files must be unique within texmf/tex.
