I tested this on Emacs 28.0.50, and a filename is still required.
Otherwise emacsclient errors out as before.
[As an aside: the main difference that I see is that with
ALTERNATE_EDITOR=emacs, `emacsclient file.txt' opens emacs directly (so
there's no emacsclient process hanging around, only emacs). With
ALTERNATE_EDITOR as the empty string, `emacsclient file.txt' starts a
daemon Emacs (so there are emacsclient and `emacs --daemon' processes
running).]
That said, you can call `emacsclient -c' to create a new Emacs frame.
That works if you wanted to make a desktop shortcut to do something
similar to the Emacs+EmacsW32 patched version of emacsclient, but that
means it'll always open a new frame, even if you pass it some files.
That's not necessarily the behavior people want.
No-args support in emacsclient could be nice for scripting or for things
like the etc/emacsclient.desktop shortcut. Currently that uses a
conditional to decide what to call based on whether it was passed any
files (reformatted here for clarity):
if [ -n "$*" ]; then
exec emacsclient --alternate-editor= --display="$DISPLAY" "$@";
else
exec emacsclient --alternate-editor= --create-frame;
fi
Fixing this issue could simplify that to something like: `emacsclient
--alternate-editor= %F'. However, since emacsclient.desktop handles this
already (albeit with a somewhat complex incantation), maybe that's enough.
