Description

A markdown link with anchor is rendered as a html URL page%23anchor instead of page#anchor.
On https://try.gitea.io/g/test-anchor-bug/src/branch/master/README.md
the link to "foo.md#bar" is
https://try.gitea.io/g/test-anchor-bug/src/branch/master/foo.md%23bar
but should be
https://try.gitea.io/g/test-anchor-bug/src/branch/master/foo.md#bar

The README.md content:

# test-anchor-bug

* [link bug 1](foo.md#bar)
* [link bug 2][bug2]

[bug2]: foo.md#bar

FYI,

I'm using nginx as frontal and gitea as backend.
My current workaround for this bug is:

server {
   server_name my.domain.tld;
   location /gitea/ {
      # workaround about markdown anchor issue
      if ($request_uri ~ ^(/.*\.md)%23(.*)$ ) { return 301 $scheme://$server_name$1#$2; }
      # end of workaround
      proxy_pass http://localhost:3000/;
   }
}

Just ran into this after generating some API docs in markdown. Basically all the relative links with anchors are broken.
