See https://github.com/mtth/scratch.vim/compare/master...chumakd:master (`chumakd/scratch.vim` appears to be most comprehensive right now) In particular, `mtth/scratch.vim` still seems to have the `Winleave` vs Win**L**eave bug (https://github.com/chumakd/scratch.vim/commit/1609acd2e5bd6c3a2a05a4d21217de452f46cae5) and the `:bdelete` bug (https://github.com/chumakd/scratch.vim/commit/c87fe72bd2542182c810cb729b17d6618a278928).
