For reference, here is a way to do almost the same with mq and alias. 
(Will need minor modification for windows cmd shell.)

   $ echo '[extensions]' >> $HGRCPATH
   $ echo 'mq=' >> $HGRCPATH
   $ echo '[alias]' >> $HGRCPATH
   $ echo 'checkpoint-start = qnew -q checkpoint' >> $HGRCPATH
   $ echo 'checkpoint = qref' >> $HGRCPATH
   $ echo 'checkpoint-reset = qref -X glob:*' >> $HGRCPATH
   $ echo 'checkpoint-finish = ! hg checkpoint-reset && hg qpop -qf && 
hg qrm checkpoint' >> $HGRCPATH

   $ hg init
   $ echo foo > foo
   $ hg ci -Aqm foo
   $ echo first >> foo
   $ hg diff --nodates --git
   diff --git a/foo b/foo
   --- a/foo
