svnadmin equivalent?

Hi Marc

Thanks for the detailed explanation.

I've updated https://github.com/bsdimp/freebsd-git-docs/blob/main/faq.md to
include details discussed here.

Please let me know if I've missed anything, or if I've botched something.

BTW, I wasn't sure why you needed to reset the default first. Most people
will have that or just that an the notes. There's no reason you can't add
this too that I can see, but maybe I'm overlooking something.
