Title: Arrow shape fixed in case of even modeline height

I have found an issue in get-arrow-dots function.
The result of calling ```(get-arrow-dots 'left 6 12)``` was
```
\". \",
\".. \",
\"... \",
\".... \",
\"..... \",
\"......\",
\"..... \",
\".... \",
\"... \",
\".. \",
\". \",
\" \"
```
The problem is that this arrow is asymmetrical and it wasn't pixel perfect when rendered in modeline - that looked a bit ugly to me.

But from now on, ```(get-arrow-dots 'left 6 12)``` generates the following:
```
\". \",
\".. \",
\"... \",
\".... \",
\"..... \",
\"......\",
\"......\",
\"..... \",
\".... \",
\"... \",
\".. \",
\". \"
```
Arrow is symmetrical now and looks perfectly.
Thank you.
