diff_prune.vim

This filetype plugin for diffs/patches ("diff" filetype) provides buffer-local mappings in normal and visual mode to "undo" lines of changes defined by a linewise motion or visual mode selection: leading minus signs are removed, and lines with leading plus signs are deleted.

If the changes result in a diff block or file block having no changes left, it is also removed.

This can be handy for using with the -e or --edit option to git-add, which allows you to edit a diff before applying changes to the staging area. It also seems to work for the -p or --patch option.
