Fix#2315: Gedit strips newlines when commit lacks a blank line
%B is the "raw body (unwrapped subject and body)". Since we're
displaying both, we can use that to avoid any changes to the message
content. %B was added to git in 1.7.2 (2010) in commit
1367b12ad623e28546ba40c435015d94e7fbb248, and fugitive requires 1.8.5 so
it's safe to use.
The easiest way for users to define their own maps in Gstatus buffers is
using a ftplugin/fugitive.vim file with a `b:fugitive_type != 'index'`
guard. Setting the filetype after defining the maps allows users to
maniuplate "dangerous" maps and otherwise customize mappings.
For example, in ~/.vim/after/ftplugin/fugitive.vim:
if !exists('g:loaded_fugitive') || b:fugitive_type != 'index'
finish
