Further to the above tests from me which were in graphics mode, I also did the same test with textmode as follows:
shell1$ emacs -Q # in graphics mode
A frame renders, I then start up the server:
M-x server-start
That frame stays around. Going off to another shell, I started an emacsclient, but this time in text mode.
shell2$ emacsclient -t GNUmakefile
The terminal is cleared, and the contents of GNUmakefile appear. A buffer is assigned, as I can tell in C-x C-b in the original server window.
In the minibuffer (of the emacsclient) I then go:
C-x C-v INSTALL
and the terminal returns to the shell prompt. Interestingly, the contents of INSTALL then appear in the original emacs server window, and in the buffer listing, GNUmakefile has been replaced by INSTALL when I refresh the buffer listing.
My conclusion is that this bug hasn't exactly been "fixed" with the patches to files.el and server.el, but at least in graphics mode the frame hangs around instead of the content turning up in the parent frame with the server running.
Hope that helps,
