Undo a commit and redo

<code bash>
$ git commit ...              
$ git reset --soft HEAD~1     
<< edit files as necessary >> 
$ git add ....                
$ git commit -c ORIG_HEAD     
</code>


==== Local copy of one branch from public repo ====
<code bash>
git remote add ti git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git
git remote add tilocal /home/user/mirrors/ti-linux-kernel
git fetch ti refs/heads/ti-linux-3.14.y
