Although what I pushed out at git-jc repository does not have
this, it does not mean I forgot this issue you two have raised,
nor would want to veto it or anything like that.  Just that,
unlike the one that I already committed, the proposed change
would touch rather many lines and I have not managed to
determine the extent of the damage yet.

I am willing to make (or take) a separate patch to do this one,
since I agree with Petr's "currently we happen to have just two
but it would still be better to be able to set just one than
having to change both of them in sync." argument.

I am currently waiting for community consensus, including the
final name of the variable.  I think the current consensus is
that this is a good idea, the semantics for it is to name what
corresponds to the current "$(pwd)/.git" directory, use it to
build the default for GIT_INDEX_FILE and SHA1_FILE_DIRECTORY,
and this directory does _not_ have anything to do with my
previous "the directory that corresponds to the root of the tree
structure GIT_INDEX_FILE describes".  I agree to all of the
above.
