Quick and easy management of diff settings for the current buffer.
Map the diff toggle command to a key sequence by adding the following to your .vimrc:
map <leader>dod :DiffofferToggleDiff<CR>
To toggle diff filler (see 'diffopt') as well, use:
map <leader>dof :DiffofferToggleFiller<CR>
Not really a feature of this plugin, but a useful mapping to go along with the others is:
map <leader>dou :diffupdate<CR>
