[Python-3000] Line continuation using ellipsis

I'm not sure that I am the first to bring this up, but I might as well
get it written down.
I've never liked using the backslash operator for line continuation, for
1) It requires that it be the last character of a line, meaning that you
have to insure that there's no trailing whitespace, which can be
difficult with some editors.
2) As a wise sage once said, "it looks like line noise on my monitor".
I'm not proposing to remove the feature, however I'd like to see an
alternative method for declaring statements that cross a line boundary.
I seem to recall at one point someone suggesting the use of ellipsis,
which makes a lot of sense to me:
sorted_result = partition_lower( input_list, pivot ) ...
+ pivot ...
+ partition_upper( input_list, pivot )
Parsing-wise, an ellipsis operator would have the following meaning:
Inside a parenthesized or bracketed expression, it would have the same
meaning it does now. Otherwise, it has the meaning "consume all
whitespace, including newlines".
