SPC b R passes nil to the IGNORE-AUTO argument of revert-buffer, which
causes it to prompt the user whether they want to revert from the
auto-save file. This is not the default behavior of revert-buffer;
somewhat confusingly, IGNORE-AUTO is t by default when revert-buffer
is called interactively.
Changing Spacemacs to use the default behavior of revert-buffer makes
more sense here, as reverting from the auto-save file is rarely
useful.
