Sorry for hijacking the thread, but while playing around I noticed that
a tabpage cannot be closed with the menu item File->Close (:close) for
me. Typing :close worked, so I looked at runtime/menu.vim:
\ :if winheight(2) < 0 <Bar>
\ confirm enew <Bar>
\ else <Bar>
\ confirm close <Bar>
\ endif<CR>
winheight(2) always returns -1 for me, when on a tabpage without
vertically or horizontally split windows. Maybe there is something wrong
with it, but what's the intention of the :enew in a close item at all?

Works at least with GTK+ 2 on Linux.
