Thanks for your suggestion!

If you use -f and the file is missing, you should be able to check the return
code to detect this situation. In these cases curl shouldn't actually output
any data.

I don't really see how an option like you suggest will make you, unless you
already know before how big your download file is. And if you DO know, you can
easily make a wrapper script yourself that performs this size-check.
