[Bug 1661691] [NEW] TERM=xterm enables mouse mode in vi, breaks pasting with middle mouse

[Scott Moser]

Public bug reported:

I quite often have the following work flow:

a.) lxc launch ubuntu-daily:zesty z1
b.) lxc exec z1 /bin/bash
c.) % vi foo.txt
d.) paste some thing from my X buffer (hit middle mouse button).

Somewhere between yakkety (2:7.4.1829-1ubuntu2.1) and zesty
(2:8.0.0095-1ubuntu2) this behavior changed.

Previously this all worked fine.

Now, in zesty, however an attempt to paste results in a vi error message:
 E353: Nothing in register "

to fix this, you can first disable the mouse 'a' [1]

 : set mouse-=a


I'm not sure what is enabling this, because /usr/share/vim/vimrc has the line
set mouse=a commented out.
