I think the code had no syntax or language issue before.  The
cleanup really was about style exclusively (which still is a good
thing).  'sizeof' is an operator, very much like a unary minus or
unary ampersand which neither require parentheses.  So either of
"sizeof(x)" as well as "sizeof x" are legal with regard to the C
language.  It's just that the community prefers "sizeof(x)" for
the improved readability.
