A secondary reason for adding the cg-printenv capability was that a user would
see this command in the cg-help list, and cg-help printenv would give:

Print exported git environment variables
Copyright (c) Steven Cole 2005  <--- Petr, my early version of cg-help stripped (c) lines.

These git environment variables are used in case
values other than that returned by getpwuid(getuid())
are desired when performing a commit.

AUTHOR_NAME		Author's name
AUTHOR_EMAIL		Author's e-mail address
AUTHOR_DATE		Date, perhaps from a patch e-mail
COMMIT_AUTHOR_NAME	Committer's name
COMMIT_AUTHOR_EMAIL	Committer's e-mail address

Takes no parameters.

Yes, I know that the environment variables are documented in Documentation/core-git.txt,
but having this usage right up front like this may help those who only RTFM as a last resort.

If others feel that the more obscure environment variables should be exposed here, feel
free to submit patches.

Here is a patch with Junio's improved version:

--------------------------------------------------------------------------------------
The cg-printenv command will print exported git environment variables.
