For me the reasoning is: Most people (me included) don't know off-hand
if the semantic of
a & b ? c : d
is
(a & b) ? c : d
or
a & (b ? c : d)
In some situations (e.g. a & b == c) gcc even warns when you don't add
syntactically needless parentheses. The case under discussion isn't such
an example though.
Best regards
