 I don't usually like to complain about other people's coding
preferences, but this just struck a nerve.

 This is just plain ugly.  When *I* see a comma operator, I tend to think
of two things being done in parallel, so the impression I get when
reading this segment is different from what is really going on.
 Besides, what's so doggone hard about adding a couple extra
braces and semi-colons?  

Oh well, back to my cage.
