Ok, I added comments/summaries above each test (in fact 4 of them). I wanted to
comment more on them, but I also wanted to show a sign that I care about this
issue.
Summaries are separated between some visible markers.

allow-hotplug ones should be managed, too (according to the README.Debian
examples)
1.)
auto wlan0
iface wlan0 inet dhcp
- -> This device is managed by NM.
1.a)
allow-hotplug eth0
iface eth0 inet dhcp
- -> This device is managed by NM
But I never disagreed with that :-) .

That would be ok *if* I would still be able to use the init script to stop and
start networking from the console. Since X might not start, it might not
allowing me to maneuver networking from the console until I:
1) remove NM from the system,
2) start in X and use NM to start it (which leaves the init script broken with
allow-hotplug, and partly broken with auto)
3) add a dummy hook to the interface I want to work with and restart dbus, to NM
does not handle the connection anymore
4) modify interfaces to use a static IP
All of these are suboptimal, IMHO.

--------------------------------------------------
The first situation starts with NM removed, after a reboot, with "allow-hotplug"
set in interfaces.
After "networking stop", "networking start" has no effect.
So this whole issue looks like is related both to NM and the "allow-hotplug"
vs. "auto" option.
Sorry for not provifing full information here.

This test starts without NM installed and with "auto eth0" in interfaces.
In this case the init script behaves as expected, stop is stop, start is
start, restart is restart.

As soon as NM enters the stage, things become weird, even if auto is kept:
The interface is down, (init) start has no effect until the interface is stopped
