git log <since> <until> shows all log instead of specified
git-log man page says:

>  git log [options] [since..until] [[--] path...]

>  since..until
           Show only commits between the named two commits. When either
           <since> or <until> is omitted, it defaults to HEAD, i.e. the tip of
           the current branch. For a more complete list of ways to spell
           <since> and <until>, see gitrevisions(7).


When I do git-log for some refs of the repo I get the hole log:

    $ git log HEAD^ HEAD

What should I do to be able to show log since and until some revisions?
