I've got a situation similar to the following: augroup A autocmd BufWritePre <buffer> [stuff that changes the buffer before writing] augroup END
augroup B autocmd BufWritePre <buffer> [stuff that changes the buffer before writing] autocmd BufWritePost <buffer> undo augroup END Obviously, in group A I'm trying to make a change in the buffer as well as on disk. In group B, I'm trying to only make a change to disk. The command handlers are invoked in the order seen. First Pre A, then Pre B, then Post B. The problem is that the post command in group B is undoing the changes from group A, as well from itself. The problem is that it isn't easy to reverse the modifications in Pre B, other than by invoking :undo. Any ideas?
