Hmm, It did not really migrate the options :-(

strace shows that it ignores
file:///home/pmladek/.libreoffice/3/user/registrymodifications.xcu

Instead it looks for
/home/pmladek/.libreoffice/3/user/registry/data/org/openoffice/Inet.xcu
/home/pmladek/.libreoffice/3/user/registry/data/org/openoffice/Office/Calc.xcu
/home/pmladek/.libreoffice/3/user/registry/data/org/openoffice/Office/Chart.xcu
/home/pmladek/.libreoffice/3/user/registry/data/org/openoffice/Office/Common.xcu
...

I am afraid that there is no support to migrate the optimized
registrymodifications.xcu. It think that it was new in LO-3.3 and we did
not need it to migrate from .openoffice.org/3/

I hacked MigrationImpl::copyConfig to use user/registrymodifications.xcu
instead of the single .xcu files. It did not help. It must be more
complicated.

Does anyone has a better knowledge of this pice of code?
