This does 2 things:
- it fixes the syntax for `matrix_id`. Starting strings with `@` is
invalid YAML, so such strings need to be wrapped in single or double
quotes
- it makes use of the `matrix_domain` variable instead of hardcoding the
domain name. This should be more and mistake-proof (typos or people
mistaking their domain - matrix. vs base domain)
With most people on Synapse v0.99+ and Synapse v1.0 now available,
we should no longer try to be backward compatible with Synapse 0.34,
because this just complicates the instructions for no good reason.
This is provoked by Github issue #46.
No client had made use of the well-known mechanism
so far, so the set up performed by this playbook was not tested
and turned out to be a little deficient.
Even though /.well-known/matrix/client is usually requested with a
simple request (no preflight), it's still considered cross-origin
and [CORS](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS)
applies. Thus, the file always needs to be served with the appropriate
`Access-Control-Allow-Origin` header.
Github issue #46 attempts to fix it at the "reverse-proxying" layer,
which may work, but would need to be done for every server.
It's better if it's done "upstream", so that all reverse-proxy
configurations can benefit.
