- When running diffthis (or vim-fugitive's Gdiffsplit), hunk operations
to the index will now update the diff buffer.
- Similar to vim-fugitive's Gdiffsplit, buffers of a file in the git
index can now be edited. When the buffer is written, it updates the
git index accordingly. Likewise the index buffer can also be reloaded
(via 'edit').
- Moved all diffthis code to a separate module.
Fixes#501
- blame_line() now takes a table as it's first argument (instead of a
boolean) with the fields "full" and "ignore_whitespace"
- Added config.current_line_blame_opts.ignore_whitespace
Resolves#400
