How did you get your working tree? Is this a newly created tree (where 
you run tla init-tree), or is it something that you checked out?

If this is a new tree (from tla init-tree) then there is no old version 
to compare against (since nothing has been added to the archive yet). 
You need to do a tla import first, and then you can do tla changes from 
there on.

If this is a tree that you checked out, it sounds like you deleted some 
patch logs inside the {arch} directory (probably accidentally).

The way tla tells what revision your tree is on is first by checking the 
file {arch}/++default-version to find out what version the tree should 
be. The it looks for patch-logs for that version, and the latest one is 
the revision. If you have removed the patch-logs, then it has nothing to 
tell it what revision the tree is. And thus, nothing to compare against.

I'm not sure how to get out of this state, I can think of a couple 
things, but nothing really definite.
