Hm, I was thinking about the omitted -H, not the omitted value
(which I didn't even miss, admittedly).  Then again, the variable
can't be reconstructed without the value, so I'm not sure how
valuable it would be for "typeset -p" output to retain the -H.

As an aside:  The "typeset -p" description is pretty clear about
hiding the value of -H parameters, but then what does "the option
does not apply if the parameter is specified by name" refer to in
the -H description?

	-H	Hide value: specifies that typeset will not display
		the value of the parameter when listing parameters;
		the display for such parameters is always as if the
		`+' flag had been given.  Use of the parameter is
		in other respects normal, and the option does not
		apply if the parameter is specified by name, or by
		pattern with the -m option.
