vprof -s ".venv/bin/cmd --arg val" groups "--arg val" as a string for cmd

[roaet]

This is happening with neutron-server:

λ vprof -c cmh -H 192.168.8.1 -p 8000 -s ".venv/bin/neutron-server --config-file /home/jhammond/etc/neutron/neutron.conf"
...
neutron-server: error: unrecognized arguments: --config-file /home/jhammond/etc/neutron/neutron.conf
...

Whereas without vprof works:

λ .venv/bin/neutron-server --config-file /home/jhammond/etc/neutron/neutron.conf
