Add a word `variable` and a `$` sign before variable's
name in `--bare` argument section. Without this word someone
might be confused.

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;

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,
