there seem to be a lot of subtleties about the placement of condition

for instance, the following will not substitute the matched value of
boxes into stringFormattableQ

toString[expr_,boxes_,opts:optionsOrNullPseudoPatternObject/;stringFormattableQ[boxes]]:=
	toStringKernel[expr,boxes,opts];

this will

toString[expr_,boxes_/;stringFormattableQ[boxes],opts:optionsOrNullPseudoPatternObject]:=
	toStringKernel[expr,boxes,opts];

hmm
