rootcp odd behavior

[pcanal]

rootcp tutorials/hsimple.root humm.root
WARNING: omitting file 'tutorials/hsimple.root'. Did you forget to specify the -r option for a recursive copy?

seems like it would lead to an empty humm.root

However:

rootls humm.root 
hprof  hpx  hpxpy  ntuple

So either the warning's wording need to be improved (is it meant to be akin to 'adding -r for you since it looks like your forgot it or maybe something else) or the behavior of rootcp needs to be modified to match the warning.
