fundamentally, i agree with Chris.  very strongly.  Byron feels the same way.

that said, why did Byron and i add ~ and ~user to es, where we both said that  
it did not belong in a shell when we had these debates on the rc list?  it's  
an experiment:  we wanted to see if we could add it with no effect outside of  
the globber, whether it would be useful, and whether people wanted it to stay  
in.  we also don't want people who might be potential es users to be turned  
off by our ``pedantic, religious sparticism.''  es's globber made it a little  
easier to add ~ expansion w/o changing the language than rc's, but that's a  
very minor issue.

now, please, nobody ask for job control.
