Wt

If rows to a model are inserted via a WSortFilterProxyModel (i.e. a call to WSortFilterProxyModel::insertRows()), while the current implementation asks the underlying model to insert the correct number of rows, it then proceeds to assume that only exactly one row has been added in all cases.

I created a PR on github (https://github.com/emweb/wt/pull/224) to fix this; it is based on Wt 4.11.1 and applies without issues to 4.10.4 as well.
