Code review comment for lp://qastaging/~daniellimws/vte/vte-2.91-command-notify

Putting them on hold for after GCI, still some fixes to do.
For instance, the conffiles /etc/profiles.d/vte.sh:
- wasn't updated despite not having been manually modified
- isn't sourced at startup

But even with those, the patch isn't working (no notification received, even starting your own gnome-terminal instance)
