format-patch: Generate a newline between the subject header and the message body

Browse source 
format-patch previously didn't generate a newline after a subject. This
caused the diffstat to not be displayed in messages with only one line
for the commit message.
This patch fixes this by adding a newline after the headers if a body
hasn't been added.
