Unable to remove git branch

Hi guys,

I accidentally did an 'git co -b --track origin/foo' ending up with a local 
branch '--track'. Sadly, git is unable to remove or rename that branch because 
it always interprets it as a parameter. 

As a consequence, 'git br -d "--track"' does nothing and 'git br -m "--track" 
foo' even renames the current branch, say, master,  to 'foo'. Any hints on how 
to get rid of that pesky branch?

BTW please CC me as I'm not subscribed to this list.
