Will be resolved by #2572

[bartlomieju]

Fixed in #2572

$ deno_dev htts://deno.land/std/http/file_server.ts -A
Unsupported scheme "htts" for module "htts://deno.land/std/http/file_server.ts". Supported schemes: [
    "http",
    "https",
    "file",
]

We'll probably want to update the message, but it's not crashing anymore :)
