Change in git-svn dcommit semantics?

Hi Eric,

I just updated to the latest git/git-svn (on branch 'master') and the workflow I've been using no longer seems to work:

   # review the commits I'm going to send to svn
   ziti:~/proj/bioc-2.0-git seth$ git log remotes/git-svn..HEAD
   
   # now send them
   ziti:~/proj/bioc-2.0-git seth$ git svn dcommit remotes/git-svn..HEAD

   fatal: ambiguous argument
   'refs/remotes/git-svn..remotes/git-svn..HEAD': unknown revision or
   path not in the working tree.  Use '--' to separate paths from
   revisions 32768 at /Users/seth/scm/bin/git-svn line 2190
           main::safe_qx('git-rev-list', '--no-merges', 'refs/remotes/git-svn..remotes/git-svn..HEAD') called at /Users/seth/scm/bin/git-svn line 610
           main::dcommit('remotes/git-svn..HEAD') called at /Users/seth/scm/bin/git-svn line 197

At this point, my last commit seems to have been reset (although the changes are thankfully still in my working tree). If this happens to you, you can recover the last commit like:

  git commit -a -v -c ORIG_HEAD

And it seems that the new interface requires no extra args:

 git svn dcommit

The new interface seems ok until things like 

  git svn dcommit remotes/git-svn..HEAD~2

are allowed (if ever). But it would be nice for the failure mode to not undo commits :-)

+ seth
