FYI, this bug has been fixed by Aaron Ecay [1], commit 8392a7cc, which
will be included in v0.12. Not accompanied by a test, though, so keep
an eye out for regressions.
Maybe the following might be of use to someone:
#+begin_src sh
msg_lines=25
sh -c "stty rows 24 cols 80; \
emacs -Q -nw --eval \
'(progn
(dotimes (i ${msg_lines}) (insert \"\n\"))
(goto-char (point-min))
(scroll-up nil)
(princ (line-number-at-pos nil)))'"
#+end_src
This correctly returns "20", but when running the exact same thing
with Emacs in batch mode (add '--batch' option), it returns "7" ?!?
Peace
