Sounds like you are not using the 1.1 CVS developer version... then
of course you can't have heard of ctree yet. ;)
It is derived from clist with one special column, the "tree column".
It is very similar to Netscape's "Edit Bookmarks" window.

No, GTK_SELECTION_EXTENDED just hasn't been implemented yet. This mode
also exists in Motif and Tk (with variations).

Since the "select_row" signal toggles the row immediately (you can only
connect after), you should connect to the "button_press" signal, and, 
if event->button == 2, insert your own code and stop the signal to prevent
the toggle. "return TRUE" should be enough, I think.

I only use (non-anonymous) CVS, but there may be someone doing snapshots of
the developer branch. Don't know who, however...
