My heart sank when I saw this, because I've been working on my own 
pristine-killing patch. But at a glance, my patch solves a different 
problem.  When a greedy library wasn't the first library, 
find_or_make_local_copy ignored it.

With my changes, all greedy libraries are considered, and the greedy to 
be used is chosen by the criteria library_add_choice uses:
greedies that contain the same version are preferred over
greedies that contain the same branch, which are preferred over
treedies that contain the same archive, but if there aren't any we use
the first-listed greedy.

So if you have one or more greedies, no matter where they appear in the 
path, tla changes, undo, and others will no longer produce pristines.

The practical upshot of this is that you can use your greedy to track head 
revisions, while keeping a milestone revisions (e.g. branch points) in a 
non-greedy that you can manipulate with library-add/remove (and no need to 
specify which library on the commandline).

It should apply cleanly to tla--devo--1.2--patch-50

Now I'll go look at Miles' patch.
