[tex-live] TEXMFHOME setting causes recursive search of home directory

[Poor Yorick]

Hi,

Unset environment variable $HOME and installed texlive2007 to an NFS directory,
resulting in a strange TEXMFHOME value in texmf.cnf:

	TEXMFHOME=$HOME/$HOME/texmf

This, in turn, seemed to cause kpathsea to recursively search all directories in $HOME later later on:

	$ kpsewhich -expand-var '$TEXMFHOME'
	/home/rstat//home/rstat/texmf

I had some links to some giant volumes in my home area, causing kpsewhich to appear to freeze.  The problem was previously noted in the following (rather brusque)  message:

	http://tug.org/mailman/htdig/tex-live/2006-December/011782.html

The following edit stopped the recursive search in $HOME:

	TEXMFHOME=$HOME/texmf
