Browse Source 
If an image has been tagged to multiple repos and tags, 'docker
rmi -f IMAGE_ID' will just untag one random repo instead of
untagging all and deleting the image. This patch implement
this. This commit is composed of:

        *untag all names and delete the image

        *add test to this feature

        *modify commandline/cli.md to explain this
