Last version that will (should...) work with Vim 6.0.
Version 1.7

Convert to Vim 7 lists instead of string-based lists.
Add buffer navigation (move backwards and forwards through most recently used buffers), support for scratch buffer removal.
Improved honouring of the 'confirm' vim option - thanks Magnus Thor Torfason
Added (opt-in) Ctrl-^ override support to preserve cursor column.
Minor additional improvements.
