Expected Behavior

I expect Jekyll to copy my asset files:

.well-known
├── webfinger
└── webfinger.d
    └── http%3A%2F%2Fopenid.net%2Fspecs%2Fconnect%2F1.0%2Fissuer
        └── acct%3Arobert%riemann.cc.json

My motivation is here to catch requests to /.well-known/webfinger?rel=http://openid.net/specs/connect/1.0/issuer&resource=acct:my@mail.com and use a CDN redirect to /.well-known/webfinger.d/:rel/:resource.json to hardcode the response.

Current Behavior

After a bundle exec jekyll build, I get:

.well-known
├── oidc.webfinger
├── webfinger
└── webfinger.d
    └── http:
        └── openid.net
            └── specs
                └── connect
                    └── 1.0
                        └── issuer
                            └── acct:robert%riemann.cc.json

Relevant log output

No response

Code Sample

Just create an empty Jekyll project and do:

mkdir -p webfinger.d/http%3A%2F%2Fopenid.net%2Fspecs%2Fconnect%2F1.0%2Fissuer/
touch webfinger.d/http%3A%2F%2Fopenid.net%2Fspecs%2Fconnect%2F1.0%2Fissuer/acct%3Arobert%riemann.cc.json

Then build to _site.
