And importantly, "tla logs" only lists the logs present in the current 
tree.  So if you get tla--devo--1.3--base-0 and run 'logs' in it, the 
output will be quite different from running it in a tree for 
tla--devo--1.3--patch-10.

And the result for "tla revisions" will be different again.

btw, that delta trick I showed you took advantage of this property of 
'logs'.
