Thanks, Miles and Tom.  Adding --library to the "get" does work.  Adding 
a previous revision manually did not fix it.

Also, "tla changes" is now producing pristines.  But if I change the 
order of libraries so the greedy library is first, then "tla changes" 
does not produce pristines.  The behavior of "tla changes" appears to 
vary, and I'm not sure what all the factors are.

so:
"tla get" requires the --library option
"tla get" seems unaffected by the presence or absence of prior 
revisions, at least for my case.

I believe that it's a reasonable case to have
- a non-greedy library first, so that important revisions like branch 
points can be cached long-term.  I assume putting it first means it will 
be used by manual add-remove commands.
- a greedy library second, for storing recent/head revisions.

That way, your pruning script can be far simpler than if you have to 
preserve specific revisions in the greedy library.
