DidYouMean.vim

DidYouMean.vim (GitHub: EinfachToll/DidYouMean, License: MIT) by Daniel Schemala is a small plugin that prompts for the correct filename instead of opening a new file. It’s ideal if you often type a partial filename, press tab, then accidentally open a new file because multiple filenames matched.

One reason I liked the plugin is the source is relatively easy to follow. If you’re trying to learn Vim script then you might want to look through DidYouMean.vim to see how it works.
