IMO this does only partially help, consider the following example:
$(B, Y, R, X)$
$(B, Y, R, X)$
In both lines the spacing after "Y" is way to big. I don't know if
that's a bug or just ugly. (version 2011.02.15 16:11)

+1. I normally use "$x, \dots\, ,x$" because then the spacing between
the periods looks the same as between the commas and the periods, which
I prefer. I personally appreciate the wider spacing in \dots.
