  If my Mercurial source would be "http://myserver:8080/FolderName/RepoName" and the Jenkinsfile is located in "CI/Jenkinsfile", I'm able to get this Jenkinsfile through HTTP on "http://myserver:8080/FolderName/RepoName/raw-file/tip/CI/Jenkinsfile". Perhaps this is an easy solution to avoid the full checkout?
