Re: [PATCH 1/3] setup: Provide GIT_PREFIX to built-ins

I guess external scripts can call rev-parse --show-prefix themselves?

That has always been the case, I think, and it shouldn't be a problem.

The real reason you want the new GIT_PREFIX for alias/hooks is otherwise
they would not have a way to even say --show-prefix to figure it out
themselves.

Overall I think it's a good change, btw. But it leaves it up to the
(script) user to know whether git has actually changed the cwd or not,
i.e.: Is $(pwd) where the user called us from or $(pwd)/$GIT_PREFIX?

As long as there is a way for a script to figure it out when it wants to
know, I think it should be Ok.

Isn't it just the matter of reading --show-prefix and comparing it with
what came in $GIT_PREFIX?
