I would have expected this to added to environment.c in the previous
step, but it is OK--I'd imagine you'd grab this from the environment
and carrying a piece of information from git.c to here by setenv()
followed by getenv() feels somewhat roundabout, though.

As Peff mentioned in his review in another thread, a large number of
functions in git are not reentrant, and I do not think we would want
to give the impression that those missing a warning are safe to use.
Other than that, this step looks OK. 3/4 and later would be a lot
more fun to review ;-)
