- Combine one `exists` call with an implicit `get` into a `get` with an
empty default
- Do not stop any timer in the `Highlight*` functions as this done
already by `ClearHighlights`
- Get rid of the check for existence of `w:*_timer_id` since I believe
that there is no way of it being unset in the current state. The
`_Highlight*` functions are only called via the timer so there should
always be the variable. I could also not reproduce the description in
the comment - this might have been true in a previous revision.
- Make sure that the visual selection itself is not matched. This
actually increased the performance a lot while also looking like
normally (there were some subtle differences between the highlight by
visual mode and `CursorColumn`)
