A quick and dirty

  $ git grep 'GIT_[A-Z]*[^A-Za-z0-9] .*environment' Documentation/

tells us that adding "environment variable" is probably the right thing to do, but we should not add the variable dereference '$' in front (and fix some that do spell $GIT_PAGER etc. to lose '$').

In shell, $V is a notation to always name the value in the variable, and it is clearer to refer to the variable itself without the '$' sign. '$V' means "the value that currently is in the variable V".

V=newvalue
W="old value of $V"

This is unlike C where using a variable as lvalue on the left hand side of assignment does not need different spelling as the variable is used as rvalue, e.g.

	variable = newvalue;
	another_variable = 2 * variable;

Dear Junio C Hamano,

Thanks!

What should I do next? I mean, how to achieve this? This is the first time me doing that.

Should I remove it from commit, if so, how to?

Best regards,

Mark
