This also applies to CGIs. The DOCUMENT_ROOT environment variable is
a non-standard extension so it should be avoided.

There are a number of other situations in which the document root setting
is irrelevant, such as normal aliases, mod_userdir, and mod_rewrite;
mod_vhost_alias just makes it more obvious that this is so.
The right fix for CGIs is to allow modules to participate more fully
in setting up environment variables, so that e.g. modules that do
URI->filename mapping can override the DOCUMENT_ROOT setting.
