I’ve noticed some inconsistent behaviour with the `deleteLine` command.

If the cursor is on the **last** “visual” line of a wrapped line then the cursor remains on the same line number. Note the active line number in the following screenshots before/after triggering `deleteLine`.

Before:

If the cursor is on **any other** “visual” line then the cursor moved to the line number above. Note the active line number in the following screenshots before/after triggering `deleteLine`.

I wasn’t sure if this was an intentional behavioural choice or a bug? If it’s the latter then I’d be happy to move to the issue tracker.
