It seems that a fairly common pairing in the perl source is:

	    tmpsv = newSV(0);
	    gv_efullname3(tmpsv, gv, NULL);

or generating a new mortal and passing it in.

All functions in the gv_e?fullname{,3,4} family are ultimately wrappers
around gv_fullname4(), which currently returns void, and takes a not NULL
first argument.

It would probably reduce the core's code size to change it to return SV *,
and generate a new SV (possibly mortal) if the first argument is NULL.
