Variables were originally designed not to match after a dot, in order to avoid matching struct field access, however this resulted in variables that end ranges not being highlighted. In order to fix this we match a preceding dot, only if it's preceded by at least one other dot. Attempting to match on
(\.{2,})?won't work, because the optional group allows struct field access to match even when one dot is present.
