Subject: [PATCH] branch.c: Allow "-" as a short-hand for "@{-1}" in "git branch -d @{-1}"
Message-ID: <1457176366-14952-1-git-send-email-dpdineshp2@gmail.com>
URL: https://gitlist.dev/e/1457176366-14952-1-git-send-email-dpdineshp2%40gmail.com

```
From: Dinesh <dpdineshp2@gmail.com>

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.
