This is hard to believe, so I tried your steps:

address@hidden:~/dev/emacs/emacs$ git checkout /origin/master
fatal: Could not switch to '/origin/': No such file or directory

As you can see, your first command fails to complete. I requested this
on a previous question of yours about git and I request it again: please
post the *exact* commands and its output. Otherwise, claims like what
you made above are dubious, at best.

David Kastrup also suggested to commit your changes before switching
branches, I wonder why you ignored his advice.

Over the years I used several VC systems (CVS and subversion, among
others) and git is, by far, the one that makes things easier when you
don't want to lose your changes, committed or not.

Finally, I wholeheartedly recommend to give Magit a try.
