dvtm brings the concept of tiling window management, popularized by X11-window managers like dwm to the console. As a console window manager it tries to make it easy to work with multiple console based programs.

Terminal size won't updated after resized if dvtm started using su -c #75

After running su -c dvtm, I shrink the terminal width and try to open Vim and it doesn't seem to recognize the new size:

The bug isn't limited to programs with alternate screen as in #47 but also with cat. These pictures show the output of the command ran:

Before resizing
After shrinking

The problem could be avoided if one uses sudo instead but I'm curious about the reason behind this.

Edit: I'm using dvtm 0.15.2 provided by Debian testing repository.
