When I've sorting order set to e.g. by URL or file, and open a file, instead
of it being inserted into proper place in document list, it gets just
appended to the end. Only when I open the next file, the previously opened
is reinserted properly.

Some sniffing around on my part:

In app/kateviewdocumentproxymodel.cpp, KateViewDocumentProxyModel::sort()
does get called when a file is opened, but the URL and file name for the
just opened file are empty at that point. So it sorts wrongly.

At the end of KateViewDocumentProxyModel::opened there is a commented out
call to sort(). If I uncomment it, the problem is solved, but then sorting
is performed twice on opening. (The call was commented out in
http://websvn.kde.org/?view=rev&revision=887760.)
