How can I get Emacs to revert all unchanged buffers when switching branches in git?
Solution 1:
Perhaps you'd like the global auto-revert mode. Try running global-auto-revert-mode and if you like it you can add (global-auto-revert-mode) to your ~/.emacs file.
Solution 2:
Try the revbufs package:
revbufs.elis a tiny Emacs package that safely reverts your buffers when you have files being edited both in Emacs and via external tools (e.g., code generators such as Jomtool)...
