Before (re)reading this, I was under the misconception, that when forming imperatives, the {-'eghmoH} is required on every verb which happens to be intransitive.
But now, after (re)reading the relevant kgt Ca'Non, I understand that the {-'eghmoH} is required *only* on verbs of "state of being".
So we say {yItuj'eghmoH}, {yIQuch'eghmoH}, {yIyoH'eghmoH}, but we say {yItIw}, {yIQong}, {yIHu'}, etc.
