NumberForm spaces and commas in v7.0.1

in Mathematica v4 and 5.2 to print long numbers separated by commas in blocks
of 3, i used to use something like this for example:

NumberForm[N[Pi, 10], DigitBlock -> 3]

which gave:


i.e. commas to the right of the decimal point. but in Mathematica v7.0.1  the
same statement generates number blocks separated by spaces, i.e:

3.141 592 654

i can recover the commas by using something like:

NumberForm[N[Pi, 10], DigitBlock -> 3, NumberSeparator -> ","]

but does anyone know if there is a quick fix to get the old style
commas back without having to change all my old programs in this way?
