To provide control on which @(tsee if)s represent conditional statements

we provide a function @(tsee condexpr) that is just identity
but can be used to wrap an @(tsee if) to signify that
it represents a C conditional expression instead of statement.
Without that wrapper, an @(tsee if) represents a conditional statement,
