[ale] Error with git clone, pull, or push while in screen and SSH'd into a server

[Charles Shapiro]

Really good call on Mr. Sumners part.  I'd look 'specially for GIT*
variables.  A cursory check of the man page shows
GIT_DIR,GIT_WORK_TREE,GIT_NAMESPACE.

I tend to keep my environment in ${HOME}/.envfile to ensure it stays the
same across all shells in the login.
