We upgraded a server to 18.04 and now when I start typing a python file (seems to be triggered by the .py extension) the tabs default to 4 spaces. We have decades of code that use tab characters, and it has not been our intention to change that.
I found a /usr/share/vim/vim80/indent/python.vim and tried moving it out of the way, but the behavior was still there. This is more of a vim question perhaps, but I'm already subscribed here and I figured someone would know what to do. Thanks! -- https://mail.python.org/mailman/listinfo/python-list
