workdirs: cannot clone a local workdir directory

I reported this before, but now I have a nice topic to hang it on -

I have re-reproduced the bug using a build from master as of today,
using the new worktree commands.

Reproduction:
Creating a repo `foo`, checkout --to'ing it to ../bar, then try to
clone both resulting repositories..

$ git --version
git version 2.4.4.600.g6397abd
$ mkdir foo
$ cd foo
$ git init
Initialized empty Git repository in /bar/foo/.git/
$ git commit -m init --allow-empty
[master (root-commit) c6da399] init
$ git branch bar
$ git checkout bar --to ../bar
Enter ../bar (identifier bar)
Switched to branch 'bar'
$ cd ../bar
$ cd bar
$ git status -sb
## bar
$ cd ..
$ git clone bar baz
Cloning into 'baz'...
fatal: '/path/bar' does not appear to be a git repository
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
$ git clone foo baz
Cloning into 'baz'...
done.
