Reverting a buffer can be useful once in awhile, so I did bind revert-buffer to a key. That would have done the trick, weren’t it for Emacs and its lousy defaults which include prompting you before reverting a file. It’s one thing to prompt someone when an external package is reverting a buffer for you, but if it’s done by yourself interactively…
To the source! While figuring out the right invocation, I’ve stumbled over this gem:
;; I admit it's odd to reverse the sense of the prefix argument, but ;; there is a lot of code out there which assumes that the first ;; argument should be t to avoid consulting the auto-save file, and ;; there's no straightforward way to encourage authors to notice a ;; reversal of the argument sense. So I'm just changing the user ;; interface, but leaving the programmatic interface the same.
Way to go.
