What are the intended semantics? If my machine has /etc/mailname
filled out, is that an implicit identity? How about if I set the
EMAIL envvar but not GIT_COMMITTER_EMAIL?
If external scripts are going to start using this mechanism, they will
need answers to these questions to support users that run into
configuration problems. A few words on this in the documentation
could probably help.
On most machines I have the EMAIL envvar set explicitly, but in the
recent past I relied on /etc/mailname on some others, so I'm also
genuinely curious about the use case here (and too lazy to dig it up).
