 *
 * Implementations should set @a *props to the hash of properties
 * associated with @a repos_relpath in @a revision, allocating that hash
 * and its contents in @a result_pool. Only the 'regular' props should be
 * included, not special props such as 'entry props'.

 * Implementations should set @a *filename to the name of a file
 * suitable for use as a delta base for @a repos_relpath in @a revision
 * (allocating @a *filename from @a result_pool), or to @c NULL if the
 * base stream is empty.
 *
 * Any output argument may be NULL if the output is not wanted.
 *
 * @a baton is an implementation-specific closure.
 * @a repos_relpath is relative to the repository root.
 * The implementation should ensure that @a new_content, including any
 * file therein, lives at least for the life time of @a result_pool.
 * @a scratch_pool is provided for temporary allocations.
