You can say "git checkout @{-1}" to go back. That is the commit you came _from_.

But I think what you were computing for $that_commit was different. It's "the ref that is checked out, even if it's detached".

After doing:

	: start from anywhere
        git checkout master	;# on master
        git checkout branch~4   ;# detach at that commit
        ... hack hack hack ...
        git commit; git commit

your @{-1} is 'master'; "the ref that is checked out, even if its' detached" is 'branch~4', and that is what you want as $that_commit in the example. That shows your _progress_, which has no relation with 'master' that is @{-1}.
