I saw it, but as there were two patches of Ivan, I understood
that the 2nd one (which would even group X11 windows of
unrelated R instances) was unneeded.
I concluded I liked the first one because it would achieve
what's considered "uniformly better" in the sense that it makes
R graphics behave like "all other" desktop applications *and* it
would do so for all possible window manager scheme without any
need of some desktop setting (which a typical user would not
know about, nor know that s?he should/could change).

a big "iff" at least conceptually, when in the present case,

What about Redhat/Fedora etc, what about the next cool window manager
on Linux distribution Z? They may change to do what .desktop
does in a different way, etc, or more typically not package R
that way and hence not have a *.desktop equivalent.

which probably also depends on your screen size and the
configuration of several tuning parameters of your window
manager etc..
This all started with Dirk saying the R behaves differently than
"all" other applications in this respect, and Ivan found compact
way to change that .. window-manager -- independently which I
still think is a pro.
Given Duncan's use case, may this should become an argument for
x11() and X11.options(), say grouping = c("process", "none", "all")
with match.arg(grouping) used, so the default was "process"
i.e. group things together that belong to the same "process"
(current R-devel), "none" would correspond to the previous
default and "all" would correspond to what the 2nd patch of Ivan
aimed for.
