add options to make appearance more like original `sindrets` repo

[dlyongemallo]

Based on this comment from user @shmerl:

In your fork, it started adding colors in the files pane which I don't think the original did. Like added / removed styling to number of changes I guess? And something also in the signs column looks different than before, too noisy for me. Is that configurable?

Hi! My request does not strictly belong to this issue because the marking feature is not present in the original plugin, but it is about the appearance, so here it is: I would appreciate if it was possible to configure the position of the "(un)marked" signs. I think it would be less distracting if the marks were placed to the very left of the file panel, see examples in this comment.

Try the following config with PR #90 and let me know if that works for you or not.

file_panel = {
    mark_placement = "sign_column",
    always_show_marks = false,  -- or true
},

Works like a charm! Thanks!

@dlyongemallo I noticed when switching from the original repo that the folds in the diff files are automatically opened. Is there a setting somewhere to change that back to the previous behavior?

This is implicitly described (you need to set foldlevel to 0 to get the original behaviour) in the very last section of the compatibility issues. I think it could be documented more prominently right in the README.

In retrospect, maybe the default value of 0 makes sense (a major use case for diffview.nvim is code reviews where collapsing non-diffs is a sensible default), and users of other plugins which create folds can set the foldlevel explicitly to a higher value.

[dlyongemallo]

@nathanzeng I've added a view.foldlevel option to set this easily.

@dlyongemallo @jakubbortlik Thanks for the responses. The new default you've set fixes it for me. Thank you for your work on this fork!

Hello, is there an option for the diff1_inline layout view to not use virtual lines for the deleted diffs? The background from the virtual lines gets cut off where the text ends and it looks kind of weird, it would be nice if it would just use the DiffDelete highlight.

diff1_inline:

Compared to diff2_horizontal:

We could even get rid of the DiffviewDiffDelete highlight altogether.
