It could be argued that the observed behaviour is a bug, by the way.

If we followed the normal "command line options trump environment
variables that in turn trump config variables that in turn trump
whatever the default values we compute using cues from the system"
precedence order, EMAIL ought to come between the more specific
GIT_{AUTHOR,COMMITTER}_EMAIL environment variables and the configuration variable.

But reading the value of EMAIL can also be seen as part of the
"using cues from the system" (it often is set in equivalents of
"$HOME/.profile" by equivalents of "adduser") step, and the original
motivation to add indeed was to allow users to override
EMAIL (or the name we grab from the system) without having to set
the GIT_COMMITTER_EMAIL environment variable.

So the current behaviour is correct, and the patch is a good
(belated ;-) update to the documentation.

Will apply.  Thanks.
