That's not how I read this (from HACKING):

    * Signify internal variables by two underscores after the prefix.
       That is, when a symbol must (for technical reasons) reside in the
       global namespace despite not being part of a published interface,
       then use two underscores following the module prefix. For
       example:

          svn_fs_get_rev_prop () /* Part of published API. */
          svn_fs__parse_props () /* For internal use only. */

Even though the paragraph above discusses variables, the examples are clearly
functions, and they strongely suggest that the double underscore functions are
not part of the public API (for compatibility purposes).

If I have misunderstood, please enlighten me. Is the "published API" simply the
collection of all functions defined in the .h files?
