[BUG?] Detaching head at checked out point does not work.

[BUG?] Detaching head at checked out point does not work.

Hello,

I can correctly detach head by saying:

  git checkout master^0

(or git checkout master^{} or git checkout refs/heads/master), but NONE of
these work, if I currently have master checked out. Shouldn't it detach
anyway?

Regards,

Jan

Yes, and it does as far as I know.

Do you have 3e0318a3?

commit 3e0318a3613ae8e89dcb1fc39d909145e64287b9

    checkout: allow detaching to HEAD even when switching to the tip of a branch
    
    You cannot currently checkout the tip of an existing branch
    without moving to the branch.
    
    This allows you to detach your HEAD and place it at such a
    commit, with:
    
        $ git checkout master^0

It does not seem to be in 1.5.1.4, so no, I don't.

I apologise for not looking whether head has a fix.

As that commit is directly on top of v1.5.1, I think it may not
hurt to cherry-pick that single commit to 'maint' for 1.5.1.5,
although some may argue that it is not strictly a bugfix but a
new feature.

I would not call it a new feature, since it worked if I had something else
than master checked out. It is not a regression though and given that 1.5.2
is getting closer I'm not sure it's worth bothering.
