Nah. What's the point of having another protected name. Just allow

	$ git checkout -b discard HEAD~15

and we're good to go.

It wouldn't on cygwin, for one. I'm against having things work 
differently on different platforms. If nothing else it usually worsens

branches, and although merging any changes from it might be more trouble 
than its worth, it might be possible to cherry-pick the commit rather
