Among the two unrelated changes that are not mentioned in the
proposed log message, the change to the test to use sane_unset is
probably OK, but replacing a call to getenv() with git_env_bool()
without making sure necessary header file(s) are included would
break the build.

I _think_ config.h is the header to include; I didn't try it,
though.

Thanks.
