Yeah, that's what I expected. Turns out it wasn't so bad in the end ;) 

Here's the solution. $- contains 'i' if the shell is interactive (which
it's not when invoked through scp or ssh), so this does it:

INTERACTIVE=`echo $- | grep i`
if [ -n "$INTERACTIVE" ]
then
  # interactive-only commands
fi
