feat(panel): add list_options.path_style option for full path display

[saviocmc]

• Add file_panel.file_name_style config option ("basename" or "path")
• When set to "path", file entries in the file panel show the full path (parent_path/basename) with uniform highlighting, instead of the default behavior of showing only the basename with a dimmed path appended after it

Usage:

require("diffview").setup({
  file_panel = {
    listing_style = 'list',
    file_name_style = "path",
  },
})

Thanks @saviocmc for the contribution!

Please update doc/diffview.txt and add the option to the file_panel section, and likewise doc/diffview_defaults.txt.

Thanks for the feedback! I agree with the suggested changes and added the documentation as well. Thanks for maintaining this fork!

now the config is:

require('diffview').setup({
    file_panel = {
        listing_style = 'list',
        list_options = { path_style = 'full' },
    },
})
