Tim Edwards d6cadeb0cd Decided that "lef write -hide" should always use widespacing rules, ...

because otherwise all pins will flag metal-to-obstruction spacing
within the cell if the cell is wide enough that the obstruction
layer satisfies the width requirement for the rule.  It is too
complicated to try to find specific places where the wide spacing
might not be needed.  Potentially this could be a problem for
technologies that define a number of graded wide-spacing rules,
as the largest-width rule is always used now by "lef write -hide",
and the largest-width rule could theoretically allow enough space
to route through, which would cause a short that cannot be
detected.  That would be a pathological case that may not show up
in practice.
