   This works beautifully.  My command is just a wrapper to scp, written
to help prevent overwriting of files.  Too many times I've omitted the
remote destination argument--i.e., scp source1 source2--and overwritten
source2 with source1.  (I'm not aware of any interactive option for scp like there is for cp.)

   So, this command lends itself perfectly to compdef.  I am in your
debt.  Thank you!
