Repeats with partials and alternatives

[Roman Stawski]

I think that there seems to be a problem with the way the repeats and 
alternatives
are handled

In the page 
http://lilypond.org/doc/v2.2/Documentation/user/out-www/lilypond/Repeat-syntax.html#Repeat%20syntax 
(documentation for repeat syntax) the last example seems
strange. The second alternative follows on from the end of the first, 
rather than
from the end of the common part of the repeat. The bar checks just mirror this
behaviour.
