[ESS] Strange behaviour of ess-eval-buffer-from-beg-to-here?

[Vitalie Spinu]

It's indeed a peculiar situation. It happens on `C-c C-c` as well and
has nothing to do with ESS (on the emacs side). The emacs process
filter is not even receiving any output after the first matrix. I am a
bit puzzled of what could cause that at the moment.
