Unlike other environment variables (e.g. GIT_WORK_TREE,
GIT_NAMESPACE), it was not possible to set the GIT_INDEX_FILE
environment variable using the command line.

Is this necessary?  I'd prefer to see a better reason than "just
because others have it".

A long running program will be able to tell git to use an alternate
index file, without having to modify its own environment,...

Hrm, isn't that the single-shot environment export syntax

	GIT_INDEX_FILE=foo git blah

is for?  Is there a real-world need for this?
