Close the empty pipeline upon return

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Do something like "make", wait until it's done.
2. Then press Enter, and hotwire should close the pipe
3. Way easier than remembering shift+ctrl+k and pressing that combination!

What is the expected output? What do you see instead?
When hotwire says "Failed to parse pipeline: Empty pipeline", upon return
it should quit.

What version of the product are you using? On what operating system?
Latest svn version (936), Ubuntu 7.10.

Please provide any additional information below.
Let me know if any clarifications are needed!

One thing that I've realized is that we don't have Ctrl-Shift-K in the 
tutorial. 
Adding something about it might help with this situation. 

Is it just that Return is easier to type, or you expected things to go away on 
Return?

Maybe we could use a 'clear' builtin which clears the current tab?

Both - easier to type, and expect it to go away on return. I think hotwire 
already
does that in some place.

No, I don't think a clear is needed.

I would not expect the current result to go away on return.  I would wonder 
what had
happened and be confused.

Just played with Ctrl-Shift-K and it could be handy sometimes.  A clear builtin 
would
be useful (maybe default to clear one output, -a to clear all?).

I do think that pressing return when nothing is typed (or only whitespace has 
been
typed) should be a no-op.  It's a bit annoying to have that pop up when you 
haven't
done anything ...
