Bad formatting when an item starts with `_`

The following items:

```
Switch test1               "test 1"                                     (All)
Switch _test2              "_test 2"                                     (All)
```

align to:

```
Switch    test1    "test 1"    (All)SwitchSwitch _test2              "_test 2"                                     (All)
```

which is obviously wrong.
