While apparently more important for VCs that keep the entire
repository history locally, a VC-aware "copy" operation would benefit
CVS, SVN, etc. as well by avoiding each VC's specific administrative

I'd think that having the VC-specific code implement the copy
operation would be the right way to do this. For example, a
subversion mode would be like "cp -rp" but it would exclude the .svn
That's probably more than you were planning on tackling but perhaps
you could file an enhancement request so that all VCs benefit.
