For argument parsing I'd prefer to make spaces significant.
The basic problem is having to parse a set of arguments with
no delimiters to separate them. This is never going to be easy
or satisfactory, given the complex existing syntax, and will lead
inevitably to user surprises. Keith spotted this one; I'd be
surprised if it were the only one.
