OK, how about doing this then?

Yeah, I do not think of a reason why it should fail in a bare
repository, either. "git archive" is about writing out the contents
of an already recorded tree, so there shouldn't be a reason to even
call get_git_work_tree() in the first place.
Even if the code is run inside a repository with a working tree,
when producing a tarball out of an ancient commit that had a
submodule not at its current location, --recurse-submodules option
should do the right thing, so asking for working tree location of
that submodule to find its repository is wrong, I think. It may
happen to find one if the archived revision is close enough to what
is currently checked out, but that may not necessarily be the case.
At that point when the code discovers an S_ISGITLINK entry, it
should have both a pathname to the submodule relative to the
toplevel and the commit object name bound to that submodule
location. What it should do, when it does not find the repository
at the given path (maybe because there is no working tree, or the
sudmodule directory has moved over time) is roughly:
- Read from .gitmodules at the top-level from the tree it is
creating the tarball out of;
- Find "submodule.$name.path" entry that records that path to the
submodule; and then
- Using that $name, find the stashed-away location of the submodule
repository in $GIT_DIR/modules/$name.
or something like that.
This is a related tangent, but when used in a repository that people
often use as their remote, the repository discovery may have to
interact with the relative URL. People often ship .gitmodules with
[submodule "bar"]
URL = ../bar.git
path = barDir
for a top-level project "foo" that can be cloned thusly:
git clone git://site.xz/foo.git
and host bar.git to be clonable with
git clone git://site.xz/bar.git barDir/
inside the working tree of the foo project. In such a case, when
"archive --recurse-submodules" is running, it would find the
repository for the "bar" submodule at "../bar.git", I would think.
So this part needs a bit more thought, I am afraid.

Jens already commented on this, and I agree that --recursive should
be dropped from this patch.
