Re: feature request - implement a "GIT_AUTHOR_EMAIL" equivalent, but processed BEFORE .gitconfig

I wouldn't mind having a GIT_EMAIL envvar with the semantics you mean,
but can you say more about the use case?  What's wrong with the usual
EMAIL environment variable?

EMAIL actually worked for this case for me, but there wasn't any
equivalent for author name, so the commits all look like
"sharedaccount <myuser@mydomain>".

I do not want to go into the discussion on the sanity/insanity of
using such a "shared account", but I am guessing that you already
have a concrete and workable mechanism in mind to allow you to set
these environment variables such as GIT_WEAKER_AUTHOR_NAME to
individual real users who share that account, and I further guess
that that is what you use to set EMAIL.  Am I guessing right?

If so, wouldn't it be a better option to use that mechanism to set
separate $HOME (or XDG_CONFIG_HOME if you prefer) to these real
users who share the account, so that separate $HOME/.gitconfig files
can be used by them?
