Tabs, Spaces, and All That

Xah Lee has a helpful post on dealing with tabs, whitespace, and indentation. Nothing in the post qualifies as advanced and most of you will be familiar with the material but I remember being confused about tabs and indentation when I first started Emacs so n00bs may find it helpful. The Emacs tab behavior is rich and complicated. Vim (and other editors with which I’m familiar) tend to be more straightforward but less flexible so n00b confusion is understandable. In any event, Lee’s post is worth a look.
