+
+       Rework the way completion works in GtkFileChooserEntry.  Fixes
+       http://bugzilla.gnome.org/attachment.cgi?bugid=314873 - 
+       Tab completion should work even if the cursor is not at the end of
+       the entry.
+
+       * gtk/gtkfilechooserentry.c: Change the strategy by which we do
+       completion.
+
+       We distinguish between two cases:
+
+               - autocompletion - happens only in the Open modes by
+                 inserting and selecting the common prefix as you type.
+
+               - explicit completion - happens when you hit Tab.
+
+       When some type of completion needs to happen, the entry first
+       parses its input and sees if it needs to initiate a folder load.
+       Completion will not happen until the folder finishes loading.
+
+       If the folder is already completely loaded, then completion is
+       performed immediately.  Otherwise, the entry queues a pending
+       completion and starts loading the new folder (or waits until the
+       current folder is completely loaded).
+
+       Tab completion is allowed to happen even if the cursor is not at
+       the end of the entry.
+
+       There is a new feedback mechanism for explicit completion, so that
+       you will get an Emacs-like tip whenever there are ambiguities in
+       completion, no matches, etc.  (This needs to be polished so that
+       we support RTL entries and all the fancy Pango layout in GtkEntry).
+
+       The only remaining thing to fix is the popup suggestion window.
+       Unfortunately, GtkEntryCompletion does not let us do what we want,
+       and will need further changes.
