Re: interactive "r" argument passing

Thanks, again. The problem wasn't with the function but with a faulty 
defalias form, with which I called the function. Now I have (correctly):

(defalias 'sch 'save-sscratch)

I was losing the contents of *scratch* because  of unexpected shutdowns 
and because that buffer is not normally associated with any file. Maybe 
it would be a good idea to save the buffer to starscratch.txt on start 
up so that later it might be recovered if need be (with 
recover-this-file). Emacs dev would know how to make it do what I mean.
