What do you mean "the comments will move"? Comments within a single
block will not be affected at all by the change of tabstop, as the
tabstop change affects all lines within the block equally. Of course,
comments from different blocks will not be aligned, but you shouldn't
expect them to be. Consider that with the style you recommend below
(ts=8 and sts=4), you will have much worse problems than comments from
different blocks not aligning...
