Hopefully not, since one of the goals here is to be able to accept 
arbitrary strings from other programs (e.g. your mailto: handler). If we 
required strings to look "like this", then it becomes much more 
difficult to ensure that internal quotation marks are properly escaped.

Instead, I think the arguments passed this way should always be strings. 
If you need something fancier, --eval can step in. (Of course, a 
function called with --function can convert its arguments however it likes.)
