scp could parse the arguments locally. I can only see three cases:

1) scp is called with two file arguments:
scp remote:/x/y/file /local/file

in this case, scp should deny any access to files other than /local/file

2) scp is called with one file and one directory:
scp remote:/x/y/file /local/dir/

in this case, scp should only allow writes to /local/dir/file, and especially
not to files in subdirectories of /local/dir/.

3) scp is called with -r and two directories:
scp -r remote:/x/y/dir/ /local/dir/

in this case, scp has to allow writes to /local/dir/* and subdirectories,
but the user should expect that, so its probably ok. 


(I said scp, rcp is the same, of course)
