如何在Python中遇到空行时将vim设置为unindent？

Question

It could be useful if vim could do a unindentation automatically when I type an empty line, but it seems it is not the default behavior. This would especially useful for Python, could Vim be configured to do so?

I made some mods to my own indent/python.vim to enable full dedent when the third empty line is entered. You may be able to adapt this to your needs.
