The reason for this weird behavior is that we removed almost all the
variables from setuptex back in May 2009.

This is just the contrary of what Hans tried to achieve several years
ago to overwrite the tetex's pollution with variables. Now that hardly
anyone uses tetex ... we didn't bother about that any more, but it is
still a problem if one sets up an old distribution in .bashrc and then
tries to use a new one. (In that case the old ConTeXt behaves just as
impolitely as tetex and hinders the ability to use the latest one.)
