There is no mention of what happens if sz==size(). While it obviously does nothing I feel a standard needs to say this explicitely.
[ Resolution proposed in ballot comment ]
Express the semantics as pseudo-code similarly to the way it is done for the copying overload that follows (in p3). Include an else clause that does nothing and covers the sz==size() case.
[ 2010 Batavia ]
Accepted with a simplified resolution turning one of the < comparisons into <=.
Ammend [list.capacity] p1:
void resize(size_type sz);
Effects: If sz < size(), equivalent to list<T>::iterator it = begin(); advance(it, sz); erase(it, end());. If size() < sz, appends sz - size()
default constructedelements to the sequence .
