Thank you for including the constructor bypass patch.  I think we should
include a couple of notes:

1) While those interested in high performance computing will generally want
this change, it will break old code that assumes that a
ublas::vector<Complex> is initialized to all zero (none of us write code
like this, of course).

2) The constructor bypass uses partial specialization.  I think we are safe
to assume all supported compilers have this?  If not we can add the
appropriate ifdef.
