I do not necessarily think --prefix=untar/it/here/ is a work
tree operation.

Perhaps we probably are better off if we add something that says
specifying GIT_DIR alone means you are at the top of work tree
(to resurrect the traditional behaviour), to alleviate fallouts
like this and the other cvsserver one?  If one does not like
that traditional behaviour, the new GIT_WORK_TREE support can
be used override it.
