Yup, --expand-path culls those path elements that do not exist.

	$ kpsewhich --expand-path '/a/b/c'
        
	$ kpsewhich --expand-path '/tmp'
        /tmp

The other part is that default expansion works on "formats" not
environment variables.  Example:

	$ env TTFONTS=/tmp: kpsewhich --expand-path '$TTFONTS'
        /tmp
        $ env TTFONTS=/tmp: kpsewhich --show-path=.ttf
        /tmp:.:/home/olaf/texmf/fonts/truetype//:!!/var/lib/texmf/fonts/truetype//:/usr/local/share/texmf-local/fonts/truetype//:!!/usr/local/share/texmf/fonts/truetype//:!!/usr/local/share/texmf-dist/fonts/truetype//

This is because more than one enviroment variable can used to
determine the .ttf path.
