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 or is omitted, it defaults to HEAD, i.e. the tip of the current branch. For a more complete list of ways to spell and , see gitrevisions(7). When I do git-log for some refs of the repo I get the hole log: ``` $ git log HEAD^ HEAD commit 1e939a4f7097efd03b8a66607b561c5f698b3082 Author: Vasiliy <dixel@unen.(none)> Date: Wed Apr 11 13:58:03 2012 +0400 3 commit commit 1da7dcfc1920130f3de9a7c6b8f02d68923d12b7 Author: Vasiliy <dixel@unen.(none)> Date: Wed Apr 11 13:57:50 2012 +0400 second commit commit ee8d884f5fb364f667f8dcbf27b23afb3a4eeb85 Author: Vasiliy <dixel@unen.(none)> Date: Wed Apr 11 13:57:31 2012 +0400 first commit $ git branch * master ``` What should I do to be able to show log since and until some revisions?
