Ah, I thought constructors and assignment operators were semantically
different.  If that's the case it would surely be wrong for the compiler
to substitute one for the other.  Scott Meyers, in his (now rather old?)
book "Effective C++" claims that the compiler has to create a temporary
object which is then passed to the assignment operator.  That would
account for there being two contructor calls.

But aren't QStrings shared?  So either way is should be just a matter of
increasing a count in the shared object.
