/* Wrap @c svn_ra_reporter3_t in an interface that looks like
   @c svn_ra_reporter2_t, for compatibility with functions that take
   the latter.  This shields the ra-specific implementations from
   worrying about what kind of reporter they're dealing with.

   This code does not live in wrapper_template.h because that file is
   about the big changeover from a vtable-style to function-style
   interface, and does not contain the post-changeover interfaces
   that we are compatiblizing here.

   This code looks like it duplicates code in libsvn_wc/adm_crawler.c,

   things; this code makes a new thing look like an old thing. */
