Yeah, so it was my fault for not paying attention to the = in the
command that you included as example (sleep deprivation has its
consequences...), not that you explanations were not clear -- sorry, and
thanks for the patience...

Actually it was not a "bug" in the sense that it still applied the
actions as it should -- it was instead an spurious warning, because I
had not taken into account this important use-case when I implemented
the new, leaner way to mark packages as auto-installed, on hold, etc.
So I printed those lines as a kind of "canary" to alert us about cases
where code would be invoked and when (in theory) it shouldn't, but in
the end it was just that, that I forgot that there were legit cases to
invoke that code.
We could avoid some (small) duplication of code, which is what I hoped,
but at the moment the fix is just to avoid printing the warning and add
a comment to the code to remind me about this, should I, or somebody
else, manage to forget about all the implications if attempting to
remove it again in the future.
