An improved version of this script exists here. It adds some keybindings and the ability to open buffers in split and vertically split windows.
Script has not been updated since 2004.
fholgado is working on an updated version at https://github.com/fholgado/minibufexpl.vim
- Check also http://fholgado.com/minibufexpl
- there are errors from regular expressions when the buffer name contains "~" - like foo.txt~
