This patch allows the usage of "-" as a short-hand for "@{-1}" in 
"git branch -d @{-1}".

Note : This is a microproject that is part of the Google Summer 
of Code application process.I am interested in working on the git 
Beginner mode implementation as part of Google Summer of Code. The 
mentor details for this particular project are not available on 
the Ideas page. The mentors are likely on this mailing list, so 
I request the mentors to drop me a mail so I can get in contact 
with you to further discuss the git Beginner mode project.

The "-" shorthand can be used as a replacement for "@{-1}" to refer 
to the previous branch the user was on in the "git branch -d @{-1}" 
command.Replace "-" argument with "@{-1}" when the command line 
arguments are parsed.
