Redirects of gh-hosted pages to custom domain

You can add a domain-level redirect e.g.

[[redirects]]
  from = "https://wiki.asellus.org/"
  to = "https://asellus.org/wiki/"
  status = 301
  force = true

I suspect (I have not tried) that adding a :splat (as below) may in turn negate the call from the proxy causing an infinite loop

[[redirects]]
  from = "https://wiki.asellus.org/*"
  to = "https://asellus.org/wiki/:splat"
  status = 301
  force = true

In this case I believe the proxy would get redirected back on itself and fail.
