Ctrl+Alt+Space to select line without final line break

Works just like standard Ctrl+Shift+Space but omits final `[\r]\n` from selection. Subsequent presses select more lines.

```
li|ne 1       // or li[ne] 1, etc.
line 2
line 3
```

```
[line 1]
line 2
line 3
```

```
[line 1
line 2]
line 3
```

```
[line 1
line 2
line 3]
```
