Scrolling in CSV data with newlines in columns is able to crash tabview #16
Description
If I display a file where multiple cells in a column have newlines in them and scroll along, this is able to crash tabview with the following traceback:
Traceback (most recent call last):
File "/usr/bin/tabview", line 41, in <module>

File "/usr/lib/python3.4/site-packages/tabview/tabview.py", line 530, in view

return func(stdscr, *args, **kwds)

_curses.error: addwstr() returned ERR
I still have to extract a minimal reproducable case.
