Re: [PATCH] rebase: rebasing can also be done when HEAD is detached

Kaartic Sivaraam [off-list ref] writes:

In a repository when attempting to rebase when the HEAD is detached
and it is already up to date with upstream (so there's nothing to do),
the following message is shown

        Current branch HEAD is up to date.

which is clearly wrong as HEAD is not a branch.

Handle the special case of HEAD correctly to give a more precise
error message.

 In this patch, I basically assumed that there would be no
 branch named "HEAD".

Perhaps time to learn "git symbolic-ref HEAD" and use it instead of
depending on the name?
