SCCS and similar tools are usually used by more experienced people who are 
expecte to have more knowledge on portability than a typical user of "gls".

Then I don't understand the purpose of you test as it seems to verify that 
there is no such automatic switch to binary mode.

Well, do you agree that -n and -i should be interpreted as equivalent and that 
you should accept "admin -r2 -n s.foo"?

Well, I offered my extensions to Sun a few years ago but apart from a note that 
showed interest, nothing happened. This is why I started to believe that the 
vendors might not have interest.
