Vector shuffling

Hi, Richard
There is a problem with the testcases of the patch you have committed
for me. The code in every test-case is doubled. Could you please,
apply the following patch, otherwise it would fail all the tests from
the vector-shuffle-patch would fail.
Also, if it is possible, could you change my name from in the
ChangeLog from "Artem Shinkarov" to "Artjoms Sinkarovs". The last
version is the way I am spelled in the passport, and the name I use in
the ChangeLog.
Thanks,
Artem.
