vc-got-stage is a minor mode for vc-diff buffers controlled by Got. It's a tentative at implementing the stage operation for specific changes instead of whole files. vc.el works with filesets, and this is fine. But sometimes you want to commit only certain hunks. This initial implementation allows the user to stage changes, but you can't commit them (yet).

it shows an extra commit, but it's a start!

it still doesn't work, but at least now it invokes the correct subcommand.

show the current branch for now

cl-pushnew can add multiple copies of the same string to a list, and add-to-list is also probably more idiomatic in elisp.

got expects arguments to diff to be relative to the worktree, it won’t work with full path (even if those full paths are valid, i.e. inside a worktree). With this in place, we can also adjust vc-got-diff to process all the files, and so now also vc-root-diff (C-x v D) works as intended.

This is optional, but with this in place `project-find-file' works as intended. Also, should we support also .cvsignore?

push can add duplicate elements, and that’s not what we want as an example.

Emacs add this ``Summary: '' string. it's quite annoying. vc-git doesn't seem to handle this specially, but maybe is git (the cli) that trims it? I need to check. In the meantime, drop it.
