Thanks for coming up with a patch! Yeah, the contribution process has some initial road blocks; I'll point them out below.

I would think this is a good commit subject as it describes the changes made superficially

Show 5 quoted lines

This describes what happens in this patch, but not why, which helps future readers of commit message more than the "what". I'm also just guessing but maybe:

    A user might have configured a repo to show diffs in a certain way,
    add the --no-* options to the autocompletion to override it easier
    from the command line.
    New in this patch is autocompletion for --textconv as well as abbreviation
    options as that needs to be flipped all the time in <example workflow>.

I wonder if we really want to expose indent-heuristic, I guess by not having it experimental any more it makes sense to do so. c.f. https://public-inbox.org/git/20171029151228.607834-1-cmn@dwim.me/

The patch looks good, but doesn't apply because the email contains white spaces instead of tabs. Maybe try https://submitgit.herokuapp.com/ (or fix/change your email client to send a patch; the gmail web interface doesn't work. I personally got 'git send-email' up and running; The Documentation/SubmittingPatches has a section on email clients, too)

Thanks, Stefan
