Prevent the "Press ENTER" prompt with quickfix window disabled on long messages

[SilverEzhik]

It appears that when I have the quickfix window disabled, going over a line with a warning/error shows the "Press ENTER or type command to continue" whenever I am on this line. This makes interacting with that line in normal/visual modes very difficult, as any action that would put me on that line would result in the "Press ENTER" prompt appearing, which is pretty annoying.

It appears that this is happening because I have :set ruler, which uses up some characters of the command line.

For now, a quick fix I found is to change line 135 of validator.vim/autoload/validator.vim from:

    let msg = msg[:expected].'...'

to:

    let msg = msg[:expected-5].'…'

This will make the validator messages use a tiny bit less space, while still keeping the ellipsis through a Unicode character.
