The fact that this behaviour has persisted this long and that no one has 
volunteered to fix it is a bit intimidating.

How large scale would the required changes be?
I assume the fact that arguments were quoted would have to be preserved 
and the implementation of all existing commands touched so that they can 
actually make use of that information (even if only if() would currently 
make use of it).

Are there any major pitfalls to look out for?
