Hi Andrew,

No, AFAICT the thread at https://debbugs.gnu.org/cgi/bugreport.cgi?bug=976
is complete.  It starts with my bug report, which begins this way,
continuing from the bug title, which is "incorrect code for
filesets-get-filelist":

  The part that treats a :tree of the code defining
  `filesets-get-filelist' is not correct and never could have been
  correct. And it does not correspond to the (correct) code from the
  filesets author.  One wonders if the GNU Emacs code was ever tested.

Thx - Drew
