There was a problem hiding this comment.
It seems like technically leading whitespace is allowed. See "Note on whitespace" on https://docs.docker.com/engine/reference/builder/.
I'm not sure if multiple spaces (or tabs?) after ARG or FROM are permitted... but in case they are, tokenizing on whitespace might be a better way to do this.
