texmf.cnf for BLU

This only makes sense, if you compile kpathsea with $VARTEXMF included
in the search path for texmf.cnf files (before everything else). This is
not the case in standard teTeX, so it is correct not to copy texmf.cnf
into the VARTEXMF tree.

It does not help to set TEXMFCNF inside some texmf.cnf file to something
that includes $VARTEXMF. For texmf.cnf files, the *compile time* path
is important (I think that we all agree on not to rely on environment
variables).

For TeX Live 5, it might be possible to do this change. One migth even
consider to include $HOMETEXMF.

Sure, you are right.
