Re: git submodule vs GIT_WORK_TREE

First of all, thanks for your detailed analysis; it cleared things up
for me quite a bit.

I am not sure if this would work in all cases, but let's assume there
is a new GIT_WORK_ROOT which will always point to the top level of a
given repository (it would stay the same for submodules, as well).

As for storage of .git, GIT_DIR_ROOT would always point to a directory
where git data is stored and GIT_DIR_NAME to the relative path within
GIT_DIR_ROOT. Admittedly, this may be rather specific to vcsh, but I
don't see any other (reliable) option to support submodules.


Thanks,
Richard
