[PATCH 1/1] stash: document stash.useBuiltin

[Johannes Schindelin via GitGitGadget]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

The stash.useBuiltin variable introduced in 90a462725e ("stash:
optionally use the scripted version again", 2019-02-25) was turned on by
default, but had no documentation.

Let's document it so that users who run into any stability issues with
the C rewrite know there's an escape hatch, and spell out that the
user should please report the bug when they have to turn off the
built-in stash.

See a few nits below, none of which are necessarily worth a re-roll.

Thanks!

Junio, do you agree, do you want to fix it up on your side?

Ciao,

I think you'd see all of them in what I've pushed out.

The last one might be a bit iffy, as we are talking about (a
possible bug in) a specific implementation of "git", as opposed to
Git as general concept, but I took it anyway.

Thanks, all.

Indeed, what you merged to `next` looks good to me, too.

Thanks,
