It's very possible that it's set somewhere else. The problem is that
the matchit plugin always sets it empty, also when it already was empty.

let restore_options = " ve=" . &ve . restore_options
set ve=

This should be change to:

if &ve != ''
let restore_options = " ve=" . &ve . restore_options
set ve=
endif

Should also happen for 'ignorecase'.
