Re: Cheap copies? Moves?

I would think the "cheapness" of the WC <-> URL or WC <-> WC copies would be
proportional to the number of locally modified files and directories in the
source/dest working copies. I would think that subversion would only copy
the actual differences and not do a dumb copy.
