Re: [PATCH 2/3] Mark some org-babel variables as safe locals under proper conditions

[Eric Schulte <schulte.eric@gmail.com>]

Could you add documentation strings to `org-babel-one-header-arg-safe-p'
and `org-babel-one-header-arg-safe-p'?  Also, would the header argument
list in the latter be better as a defvar which ob-*.el files could
let-bind to add their own additional safe header arguments?

Thanks,
