I would suggest that strict get should be the default and lazy is a  
command-line option.

Strict is what is expected by all current users of darcs-1, plus all  
users of git, bzr, monotone, mercurial, etc..

Note that this kind of unpleasant surprise doesn't arise only when  
using a remote repository.  I myself did "darcs get local1 local2",  
then, thinking that I had just made a complete copy of the history,  
did "rm -rf local1".


Fortunately, this was not my only copy of this repository, but it  
could have been.
