Yes, that looks better than either of the alternatives I gave.

I think I prefer that commas *do* appear in the zero padding, though
as Eric says, it does add some extra complication to the code.  In
the case of the decimal code that complication is significant, mainly
because of the need to figure out how much space is available
for the zeros *before* doing the comma insertion.
