My guess is that no one has changed the filesets code, so yes,
I'm pretty sure the problem is still there as reported.

The user-visible bug is what I described.  See the original
report, which is quite detailed wrt the problem.

See also the version of `filesets-get-filelist' that I sent (in
attachment throw.el).  It should be a fix.  If it does not fix
everything 100%, it is at least an improvement over the current
code, which is completely broken for :tree.

You can also contact the original author of filesets.el.  As I
said in the bug report, the GNU Emacs version does not respect
what the author wrote, and it cannot possibly work (e.g., for
:tree).

I can't really help more than this now.  I'm sure someone on
the Emacs Dev team can fix it, but there is not much interest
in filesets, it seems.

Apparently there was only one person (Chong Yidong) who took a
look at the bug report, and he just asked someone else to look
into it.  And that person never followed up (didn't even reply
to Yidong's request, apparently).
