Description of problem:
Attempting to run `sudo gvim /path/to/file` returns:
No protocol specified
E233: cannot open displayE852: The child process failed to start the GUI
No protocol specified

And then falls back to the text vim interface, rather than launching the graphical version.


Version-Release number of selected component (if applicable):
wayland-1.8.93-1.fc23.x86_64
sudo-1.8.14p3-1.fc23.x86_64
vim-X11-7.4.827-1.fc23.x86_64

How reproducible:
Every time

Steps to Reproduce:
1. Install the vim-X11 package
2. Run `sudo gvim /path/to/file`

Actual results:
No protocol specified
E233: cannot open displayE852: The child process failed to start the GUI
No protocol specified

And then falls back to the text vim interface.

Expected results:
The graphical version of gVIM should be launched.

Additional info:
This is a problem only when running under Wayland. It works fine under X11.

I'm not sure what the correct component is, so I'm going with 'wayland'. Please feel free to reassign it as appropriate. I tested this with both gnome-terminal and xterm.
