Relating to the dired problem, I patched the two files Eli stated, and
compiled up a motif client from this git commit
(emacs-29.1-89-g26949819df0) plus the two changes in lisp/files.el and
lisp/server.el. Installed to the usual /usr/local/bin/emacs and duplicated
this set of instructions:

shell1$ emacs -Q
Window opens. I type M-x server-start, window stays around. I switch to
another terminal and:

shell2$ emacsclient -c GNUmakefile
The terminal states "Waiting for Emacs..." and a window opens with content
of buffer.

In that window, I go C-x C-v INSTALL

The terminal returns, but the emacsclient window remains mapped and I'm
able to work in the newly created buffer. Both that window and the original
window with the server started are both mapped and visible.

Hope that helps,
