Please describe the problem:
Suppose I have the following text:
"Marry had a little lamb her wool was white as snow"
Now, I want in to wrap at a certain width and align to the right. I would get 
the following:
| Marry had a |
| little lamb |
|her wool was |
|white as snow|

instead of the folowwing:
|  Marry had a|
|  little lamb|
| her wool was|
|white as snow|

Does this happen every time?
yes, I tried with versions 1.10.3 and 1.12.0 of pango.

Other information:
If I use text in RTL language (tried with hebrew) and autodir set to false, 
than right-align works fine. However, when autodir set to true, the text isn't 
aligned to the right at all.
