I think this is going in the wrong direction.

This:
   target.appendRange(v.begin(), b.end());
reads worse than
   target.appendContent(v);
IMHO.

The appendVector() in IDBLevelDBCoding.h is a bad sign.

OK. (I've been doing enough STL programming lately that I don't think it's worse). How about we keep appendVector around for now but get rid of the Vector::append overload.

IDBLevelDBCoding is a giant mess - it creates a gazillion of temporary vectors which makes the encoding algorithm essentially O(n2).

I agree with Ben and was glad to see this fixed. Passing begin/end pairs into functions just to do basic operations on containers is one of the awkward aspects of STL that I don’t want to replicate. I think there are better solutions in more-modern C++. Analogous to the new for loop, which hides the begin/end.
