Subject: Add cursorcolumn (#4084)

* Implement cursorcolumn

* Add documentation

* Separate column style from line with fallback

* Fallback to cursorcolumn first

* Switch to non-fallback try_get_exact

Add new function `try_get_exact`, which doesn't perform fallback,
and use that instead because the fallback behaviour is being handled
manually.---
