Proposed resolution:

Ammend [deque.capacity]

void resize(size_type sz);

Effects: If sz <= size(), equivalent to erase(begin() + sz, end());. If size() < sz, appends sz - size() default constructedvalue initialized elements to the sequence.

[ 2010 Batavia ]

Accepted with a simplified resolution turning one of the < comparisons into <=.

Addresses GB-113

There is no mention of what happens if sz==size(). While it obviously does nothing I feel a standard needs to say this explicitely.
