At somepoint in the recent past, I tossed off a fossil upgrade, updated my repositories, and I have some interesting artifacts when I run <code>fs extras</code>:

<pre>% fs rebuild --cluster --compress --pagesize 8192 --vacuum --wal --stats
% fs extras
../foo-project.fossil-shm
../foo-project.fossil-wal</pre>

Not a big deal, but those two files definitely don't exist, but are showing up in the <code>extras</code> output.
