[RFC PATCH v2 0/6] Noobify format for status, add, restore

[Jacob Stopak <jacob@initialcommit.io>]

Take into account reviewer feedback by doing several things differently:

  * Rename this feature (for now) as "noob format mode" (or just "noob
    mode") instead of the original "--table" verbiage. As pointed out,
    this no longer ties the name of the setting to it's proposed
    implementation detail as a table. Noob mode is not necessarily the
    right name, just a placeholder for now. Unless people like it :D

  * Instead of manually having to invoke the -t, --table every time this
    format is to be used, set the config option "status.noob" to true.
    Although this is logically tied to the status command, there are many
    commands that produce status output, (and this series adds more), so
    assume that if the user wants to see the status this way, that it
    should be enabled whenever the status info is displayed.

  * When running "git add" and "git restore" while noob mode is enabled,
    perform the add/restore function as usual, but display the table
    formatted output with arrows showing how file changes moved around.
    Displaying the output in this understandable format after each
    command execution allows the noob to immediately see what they did.
    Although this series only implements for status, add, and restore,
    this output format would make sense in other commands like rm, mv,
    commit, clean, and stash.

  * Works consistently with commands that already have a --dry-run
    (-n) option. The dry run shows the exact same output, but
    doesn't actually do the thing.

  * If `advice.statusHints` is true, add a table footer with status hints.
    Shorten these hints so that they are still clear but better fit into a
    table. Make the hint text yellow to distinguish them. The hints only
    appear when explicitly running "git status", which helps the user
    answer the question "what can I do next?". Hints are omitted in
    "impact" commands like add and restore. Having hints here distracts
    from the file change moves being showed in the table by arrows.

TODO:

  * "git status" outputs myriad other information depending on the state
    of the repo, like branch info, merge conflicts, rebase info, bisect,
    etc. Need to think about how to convey that info with the new setting.

  * Some commands (like stash) might need more than 3 table columns to
    display everything clearly.

  * For destructive commands, think about adding a prompt describing the
    effect, so the user can confirm before the action is taken.

  * Fix horrible things in the patch series code.

  * Probably other things.

Play around with it! It's fun!
