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 when a syntax error or other problem renders
/etc/gitconfig buggy, until the sysadmin sorts the problem out.
Noticed while experimenting with teaching git to error out when
/etc/gitconfig is unreadable.

Hm, unlike GIT_CONFIG this applies to all git commands (not just "git
config"), so it is misleading to document them in the same place.
Here's a better patch.
