Sometimes it is useful to also have the base file accessible when
merging branches. This view still has the local file on the left and the
remote branch on the right, with the base in the middle and the result
at the bottom.
The d1o/d2o/d3o take from the local/base/remote for the current file.
I really like the way vim-fugitive show a merge conflict by having our
local index on the left (the target), and the remote changes on the
right (what we're trying to merge with our branch). The result is
obviously the file in the middle.
The d2o and d3o mappings take from local/remote for the current chunk.
I want the core and the user settings on top, all but the alias sections
and sections added by plug-ins to be in alphabetical order, then the
aliases, followed by plug-in related settings (such as git-lfs).
I like having some colors for the meta-information shown during
diff operations.
Using the `diff-hightlight` script, you can get character-level
highlights of your diffs (just like GitHub and GitLab).
