Title: Add support for Vim's _ motion

From Vim's help files:

```
+ or +
CTRL-M or CTRL-M
[count] lines downward, on the first non-blank
character linewise.

_
_ [count] - 1 lines downward, on the first non-blank
character linewise.
```

Since _ is + with a default of one less count, I added it to the same file as + and -. I couldn't directly implement it by taking away one, since a count of 0 is interpreted as no count given, so that case is handled separately.
