Be silent when performing ex commands

For some reason, without this patch I get the following:

```bash
$ vi .vimrc:10
```

leads to:

```
"~/.vimrc" [Not edited] --No lines in buffer--
"~/.vimrc" 247L, 6784C
Press ENTER or type command to continue
```

Also appears to be a few trailing whitespace changes.... no semantic change there
