I looked in the code (general/manage/cmd/copy.c) and it seems this 
behaviour is intentional, presumably because you could be copying more 
than one file (e.g. a raster and a vector) in one invocation of the 
command and it will continue and try to copy the others without stopping 
if there is an error in just one. I suppose it's debatable whether this is 
useful.
