bug#51748: 29.0.50; Emacs 29 Creates Only Emacsclient Icon in Ubuntu Dock

[J Boyko]

There are a couple of things that come to mind as a prelude to this issue:

- switched to ZSH and Oh-My-ZSH a couple of days ago.

- built Emacs 29 (latest from source) today on Ubuntu 20.04.

After installing the newly built Emacs, I noticed that the icon in the 
Ubuntu Dock didn't seem to work. I removed the icon. I then went into 
Applications and launched an instance of Emacs. It worked. I added it to 
the favorites in the dock. I closed the instance. I then went to click 
the icon again. It opened a weird Emacsclient instance, which didn't 
split the frame into three windows like it always does at startup (I 
have this written in .emacs).

To summarize, whenever I launch from the applications, I can start a 
"normal" Emacs version. As soon as I add its icon to the dock, the icon 
begins launching Emacs(client) version.

In the applications, I have three icons: Emacs, Emacs(client), 
Emacs(Terminal). None of the three icons Emacs, Emacs(client), 
Emacs(Terminal). behaves the way it used to in the dock. A fourth option 
that replicates the original behavior may be warranted. That is, we need 
something that starts an actual new Emacs instance. As many new 
instances as desired.
