"Too many redirects" on make/polyglots

[rhurling]

I just encountered a "Too many redirects" issue while trying to access ​https://make.wordpress.org/polyglots/, which has since been resolved.

When I noticed that I performed a curl HEAD request from my server (not in the same network), with the following results:

rhurling@rhurling ~  ➜ curl -I https://make.wordpress.org/polyglots/
HTTP/1.1 301 Moved Permanently

It persisted a bit longer on my personal computer (for about 2min).

Nginx ​merge_slashes wins again. Should be fixed now, let us know if you notice any other issues.
