When a syntax error or other problem renders /etc/gitconfig buggy on a
multiuser system where mortals do not have write access to /etc, the
GIT_CONFIG_NOSYSTEM variable is the best tool we have to keep getting
work done until the sysadmin sorts the problem out.
Noticed while experimenting with teaching git to error out when
/etc/gitconfig is unreadable.
