QHash::squeeze() was unconditionally calling reserve(0), which is always allocating memory (even for 0 size). This was leading to a confusing situation when calling squeeze() on a default-constructed container with 0 capacity() actually allocated memory. This is very misleading, as squeeze() is supposed to free unneeded memory, not to allocate more. This patch adds a check for non-zero capacity. As a result, nothing is done for default-constructed container. Note that this patch also affects the QSet::squeeze() behavior, because QSet uses QHash as its underlying data type.
