Of course I meant "as a filename meaning stdin".

Because it doesn't work as expected by the users of most applications? 
For example, I expected "cal -m | ed -" to edit the output of the "cal" 
command.

In the end this is a discussion about "traditional" vs "consistent" 
behaviour.

Please, don't worry. I am not an ed user. I am only playing devil's 
advocate here. I'll implement ed options as users of ed expect them to 
be. After all, ed-0.3-pre3 works as all of you expected. Doesn't it?
