Thanks to Dennis Heimbigner, there is now a draft implementation of 

  /* Rename a group */
  int nc_rename_group(int ncid, int grpid, const char *name);

in the latest svn trunk.  See the last comment in

  https://bugtracking.unidata.ucar.edu/browse/NCF-204

for status and what we still need to do, including more testing and
documentation. 

Also, if you're used to using our svn repository, note that we will be
moving from svn to github in the next few months ...
