Re: [GSoC PATCH v7] add -p: show user's hunk decision when selecting hunks

> When a user is interactively deciding which hunks to use or skip for
> staging, unstaging, stashing etc, there is no way to know the
> decision previously chosen for a hunk when navigating through the
> previous and next hunks using K/J respectively.
>
> Improve the UI to explicitly show if a user has previously decided to
> use a hunk (by pressing 'y') or skip the hunk (by pressing 'n').
> This will improve clarity when and aid the navigation process for the
> user.

> - set `hunk_use_decision` to empty string if `hunk->use == UNDECIDED` to match
