Actually, I do  *not* see any "hang of emacs" here,
but  I have seen a related bug (multiline statements) that I forgot to
report in time before release of 13.05:

It is a situation where I'm in the *R* buffer , scroll back (or "up") to a
multiline statement
and want to copy that whole statement down to the prompt in order to
possibly edit and re-evaluate it.
This used to work fine in earlier ESS version but no longer does:

Only one line is copied down to the prompt, instead of the full multi-line
R expression.

This is really very unfortunate  and inconvenient ... in those (for me
relatively *rare*) cases where
I'd want it.
