I don't use emacs, but I use vim, and I suspect I've seen the problem you're talking about. Its the one where auto-indent puts extra indentation in pasted code? This is a problem of not knowing how to use your editor. For example, in vim I either open files in tabs (and use the vim yank buffer/clipboard) in the same editor, or go into `paste` mode to paste from the OS clipboard. I'm not sure what the solution is in emacs, but I guarantee there is one.
