cmd/acme: window directories missing from fs #75
Description
If I run 9p ls acme, I see something like this:
----------- M 0 rogpeppe rogpeppe 0 Nov 4 07:29 ''
d-r-x------ M 0 rogpeppe rogpeppe 0 Nov 4 07:29 acme

None of the window directories are present (although they can be walked to) and there's that odd empty-named file with no permissions.
