Yes I can confirm that they are missing.

Now for the truly strange part...

I applied the patch you sent and ran hg stat on the repository using  
the hg I had made using make local.   stat ran without error!

So I tried running my installed hg, again no errors.  Suddenly the  
repository shouts "I'M HEALED!" and commit works as well.   Running  
verify on the repo still reports the same errors.   And stat does not  
Give the error message you added in the patch.

So my repository really isn't healed, and I'm wondering when things  
will go bad again.

The repository has certainly been moved around as I've upgraded  
machines since this repo starting in July 2006.  But there are dot  
files that have been around for a very long time and I think would  
have been before and after any big movements.
