Bug#865820: vim-common: Change of behaviour for default value of mouse is annoying

[Matt Taggart]

I am also annoyed by the new default of mouse=a, but the proposed 
workaround of 'touch ~/.vimrc' isn't enough for a couple reasons:

1) I want to be able to turn it off system wide, not just per user
2) By creating an empty .vimrc I'm potentially losing out on upstream
defaults that I _do_ want.

Is there another way to accomplish those things? Adding 'set mouse=' to 
/etc/vim/vimrc doesn't seem to work.
