automatic \once-ing [was "Re: controlling the tie "gap" [and a possible bug?]"]

Hi David,

> I am irritated that \shape applies \once automatically.

I seem to recall there are a couple of other functions which do so as well 
(though I don’t currently recall what they are).

Would it be a good idea to standardize the codebase such that functions never 
apply \once automatically, or are there good reasons not to have such a coding 
convention?

Ah! That’s useful.

Thanks,
Kieren.
