Subject: [patch] doc: marking some environment variables as such

Hi,

In doc/grep.texi some environment variables are marked with
@code{} instead of @env{}.  Attached patch fixes this.

There are some other env vars that still use @code{}, but
they refer to a "category" -- I don't quite know whether
these should be marked differently too, so I have left
them alone.

Benno
