As I mentioned in a previous post though (is this a duplicate? I seem to remember
reading this a while ago), I agree with Eli because if you use RHIDE, and
autoindent, it uses a mixture of tabs and spaces. When you move files from
machine to machine (that all have different settings) that have been autoindented
in this way, it becomes a real pain.
