Dear Moritz and Helmut,
v.what works perfectly; thanks for that. Sadly, the issue reflects
my misunderstanding. I thought the map display GUI was calling v.what
with coordinates extracted by the GUI from the mouse click. I have been
talking about the map display query tool on wx# all along, so I
apologize if I have used the wrong vocabulary to describe the problem.
File PERMANENT/.tmp/hostname/MONITORS/wx0/cmd correctly reflects
the layer request from d.vect, so it shouldn't be too difficult to get
the GUI query tool to honor that, but I'm just beginning to dig into
GRASS source code and I wouldn't want to tackle this yet.
Thanks, Dave

Thanks Helmut, Thanks Anna
I compiled the trunk version, and the map query tool now clearly behaves
differently, but not how I expected
1) it shows all layers in the map query results, regardless of what
layer (if any) was selected in d.vect
I.e.
d.vect map
d.vect map layer=1
v.vect map layer=2
all have identical results in map query. In addition, specifying layers
that don't exist emits no warning, e.g. d.vect map layer=999
works fine, and behaves the same as any of the d.vect commands above
2) it highlights selected features in yellow, and the selected features
(areas in my case) reflect layer #1, no matter what layer is requested
in d.vect. I.e. d.vect map layer=2 map queries highlight layer 1.
I had been working on this with a quite complicated imported data set,
so to isolate the behavior more clearly I created the data below
material deleted to reduce the length
Fyi

Anna committed the patch to trunk ; so if may be able to switch to trunk
for
compiling, this v.what addition is available there without the need of
manually patching.

best regards

AFAIK the map query hasn't been changed by Anna's commit.
v. what (https://grass.osgeo.org/grass73/manuals/v.what.html) has a changed
behaviour by now reckognizing the specified layer.
the same behaviour for the map query may need a separate enhancement ticket.
in the meantime would be v.what an alternative?
