a and i cannot be used as labels in Visual mode

[ggandor]

If you press either of them when selecting a label, nothing happens. Pressing them the second time works though, and the plugin jumps to the labeled target, as it should. Maybe it has something to do with a and i being text object openers, but I have no further idea about what could be the cause of this behaviour. After all, we just getchar() an input, and that's all. Interestingly, when switching to the secondary (blue) group, the problem disappears.
