Caret lost when scrolling with Ctrl+Up / Ctrl+Down

[fhurta]

When you scroll up with Ctrl+Up, the caret is lost when it reaches the bottom.

The current behavior is that the caret is forgotten at the original place so when you find the place to edit and continue with just the Up key, the editor jumps away to its original position and you have to find the place again with mouse or PgUp. This behavior is very annoying.

The expected behavior (as known from full Visual Studio, Notepad++ and other programmers editors) is that the caret is kept at the bottom line, so when you find the place you want to edit, you can continue to that line with just Up key.

The same bug (symmetrical) for Ctrl+Down.

• VSCode Version: 1.22.1
• OS Version: Windows 10

Steps to Reproduce:

1. Open any file having more lines than fits to single page
2. Scroll at the bottom with Ctrl+End
3. Scroll up with Ctrl+Up

Does this issue occur when all extensions are disabled?: Yes

i.e. This can be achieved via keybindings:

    {
        "key": "ctrl+down",
        "command": "editorScroll",
        "args": {
            "to": "down",
            "by": "line",
            "revealCursor": true
        }
    },
    {
        "key": "ctrl+up",
        "command": "editorScroll",
        "args": {
            "to": "up",
            "by": "line",
            "revealCursor": true
        }
    }

I will file an issue with the VS keymap to ask for this to be included.
