Subject: [PATCH] QVarLengthArray: use assign() for the iterator,iterator ctor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Let's avoid std::back_inserter for non-complex types, which generates a
huge amount of unnecessary code. The implementation of assign() is far
more modern.
