Am I missing > something? Yes. "git checkout f419de6eca4ca6" (on the master branch) does not give you the state on master branch at that time. Try it yourself: git checkout f419de6eca4ca6 ... HEAD is now at f419de6eca * lisp/textmodes/artist.el: Minor doc fixes. larsi@xo:~/src/emacs/bench$ ls -l lisp/emacs-lisp/load* ls: cannot access 'lisp/emacs-lisp/load*': No such file or directory And that file does exist on master at that time. git is so much fun. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
