Ramkumar Ramachandra 95eb88d8ee reset: Make reset remove the sequencer state
Years of muscle memory have trained users to use "git reset --hard" to
remove the branch state after any sort operation.  Make it also remove
the sequencer state to facilitate this established workflow:

  $ git cherry-pick foo..bar
  ... conflict encountered ...
  $ git reset --hard # Oops, I didn't mean that
  $ git cherry-pick quux..bar
  ... cherry-pick succeeded ...

Guard against accidental removal of the sequencer state by providing
one level of "undo".  In the first "reset" invocation,
".git/sequencer" is moved to ".git/sequencer-old"; it is completely
removed only in the second invocation.
