bug#37847: [PATCH] Improve client/daemon xdg/systemd experience

[Peter Oliver]

In the systemd service, I believe that Carlos was setting $0 to emacsd for the 
following effect:

$ xprop -name emacsd@$HOST | grep WM_CLASS
WM_CLASS(STRING) = "emacsd", "Emacsd"

This is because desktops use the StartupWMClass in the .desktop file to match 
which windows are associated with which .desktop file, and we want a daemonised 
Emacs to be matched to emacsclient.desktop rather than emacs.desktop.

Consequently, now that this section of the patch has been reverted, the 
following line remaining in emacsclient.desktop makes no sense:

StartupWMClass=Emacsd


Perhaps we can find a different way of setting the WM_CLASS X11 property?

Alternatively, if we merge the two .desktop files, this issue goes away.  There 
is currently some discussion of doing this for other reasons on emacs-devel.


I’ve unarchived bug 37847 in order to add this comment, and hope that that 
isn’t a breach of etiquette.  I’ll happily raise a new bug if that’s preferred.
