Allow redirect_to with fully-qualified URLs

dscho · dscho · commit 22b45b0a101f · 2024-09-20T16:25:25.000+02:00
So far, we have used the `redirect_to` directive in the front matter
only for redirecting to a relative URL.

However, in the next commit, we will want to add fall-backs for pages
that are not rendered on git-scm.com. This fall-back wants to redirect
to the git/git repository and hence does not need `relURL` treatment.
