Re: Simplify "git reset --hard"

Instead, just pass in "-u" to git-read-tree when we do a hard reset, and 
depend on git-read-tree to update the working tree appropriately.

Well, this is wrong.  Local modifications remain after your
version of "git-reset --hard HEAD". which is not what we want
from a hard reset.

... and attempting to paper it over in git-reset.sh is also
wrong.  Keep your "--hard is noop" change in git-reset.sh and
replace it with this would be the right fix.
