Calibax, I say a habitual and a historic, and sound the H clearly in both cases.
I still say forrid because it's easier to say than four head (which is probably how it got shortened in the first place). And the spelling of hiccup is replacing hiccough. By and large though I think the tendency is for spelling and pronunciation to fall in line together and irregular versions to fade away.
My mother didn't say goff, but she said orff and she; I say off and ski.
