The normal Ex command on vim doesn't operate on all lines specified by a pattern. It just does it on the current line.

Given this example text
```
Line 1
Line 2
Line 3
```
And this command
```
:0,$ normal A;
```
There should be this resulting text, as tested in vim

```
Line 1;
Line 2;
Line 3;
```

But fakevim just does the "A;" operation on the current line

```
Line 1;
Line 2
Line 3
```

I've also checked that the command ":0,$ delete" works but ":0,$ normal dd" deletes just the current line.
