Add to list environmental variables in "Environment variables" section
of git(7) which are documented on other manpages, but were missing in
the list, in the form of link to appropriate manpage (similarly to how
GIT_AUTHOR_* variables are documented in git(7)).

These are "environment variables", not "environmental".  You
have the same typo in gitweb/INSTALL, I think.

I think this should probably be listed next to GIT_DIR and
friends.

Isn't "Specifies config file" way too vague to be any useful?

If you do not describe them enough on this page, saying "there
are other environment variables that affect the operation of
git; see git-config[1] for details" without listing them is just
as useful (or, just as useless).  At least doing so would need
much less maintenance.

I wonder if it is worth it to add them in this form (the same
"usefulness vs maintenance hassle" comment applies to the
vagueness of "appropriate variable").

Everything other than GIT_PROXY_COMMAND is for http fetch, isn't
it?  At least you could say something like:

	Used to override http.* configuration variables (see
	gitlink:git-config[1])
