The patch wasn't applied, but from my side there are no outstanding
issues. I think it wasn't applied because everyone was busy with more
important things, like the new libraries for 1.29.0.

Obviously we have still to figure out which compilers do support the
NRVO, but I can't do this for compilers I don't have :) I hope the
documentation is acceptable, if it still needs refinement, please let me
know.
