[Jeff King <peff@peff.net>]

From: Chris Parsons <chris@edendevelopment.co.uk>

This provides additional warning to users when attempting to
commit to a detached HEAD. It is configurable in color.status.nobranch.

The improvements look good to me.

This patch was severely whitespaced damaged, probably due to:

  Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes

in the original, so I am resending an unmangled version for Junio's
convenience. Chris, please make sure to turn off flowed text when
sending future patches.
