Snapshot.

lindent applied to plan9file.c; how's it look to you?
If OK I can apply to the other places.

Bug fixed in sysstat; we don't put names in kstat (yet).

Debug prints.

Status:
while true do stat '#Z/regressctl' done runs forever
while true do stat '#Z' done fails in the first 5 or so iterations with
memory corruption. I suspect devstat, that's where the cases are different
but the failure happens in cunique.
