incorrect base64 format

I was using GitHub.file() to download some of the url files from Metadata.jl and found some did not base64decode correctly. Example:

file("JuliaLang/METADATA.jl", "ACME/url")

produces

GitHub.Content (all fields are Nullable):
  typ: "file"
  name: "url"
  path: "ACME/url"
  encoding: "base64"
  content: "Z2l0Oi8vZ2l0aHViLmNvbS9IU1UtQU5UL0FDTUUuamwuZ2l0Cg==\n"
  sha: "b5b82f0d5f1f349298b604abd2f1f6e77ca1ae64"
...

but file("JuliaLang/METADATA.jl", "AWS/url").content.value gives "Z2l0Oi8vZ2l0aHViLmNvbS9KdWxpYUNsb3VkL0FXUy5qbC5naXQK\n" and

base64decode("Z2l0Oi8vZ2l0aHViLmNvbS9KdWxpYUNsb3VkL0FXUy5qbC5naXQK\n")

ArgumentError: incorrect base64 format, block must be at least 2 and at most 4 bytes

Out of the 1000 files I downloaded, about a third gave this error. I'm not sure if this is an issue with how the Content gets parsed internally and need something deeper. For my own purposes, I just fixed the strings by adding a = before the \n.
