[ESS] Bug while in error=recover

[Bill Denney]

When my fingers are quicker than my thoughts, I found a bug in ESS just now.

I have error set to recover with 

options(error=recover)

And I was debugging some code.  An error popped up, and gave the stack location selection option.  I then sent more code to emacs by highlighting a region and pressing Ctrl-Enter.

Emacs then locked up and took no new input.  Pressing Ctrl-G didn't recover it.

Presumably, a fix would be to make the code that sends to R check if it is not at the recover selection prompt.

Thanks,

Bill
