Somewhere I read that you should NOT acknowledge transmissions by just
pressing PTT briefly. Now, I had never heard that before, nor done
it, but since then I think I've heard it happen.

Can someone who is familiar with this explain the PTT-ack customs so I
know how to interpret it?

You're right, you shouldn't do it. However, it's not very uncommon to hear
both pilots and ATC use this technique. Typically it's two clicks on the
mic to acknowledge the previous transmission (just like saying "copy" or
"roger").

But you shouldn't do it because it's ambiguous in meaning and sender.
Anybody could have clicked the mic - intentionally or accidentally.
