CODE_STYLE: Space around operators

    if(a) return TRUE;

    else if(b) return FALSE;

## Space around operators

Please use spaces on both sides of operators in C expressions.  Postfix `(),

[], ->, ., ++, --` and Unary `+, - !, ~, &` operators excluded they should

have no space.

Examples:

    bla = func();

    who = name[0];

    age += 1;

    true = !false;

    size += -2 + 3 * (a + b);

    ptr->member = a++;

    struct.field = b--;

    ptr = &address;

    contents = *pointer;

    complement = ~bits;

## Platform dependent code

Use `#ifdef HAVE_FEATURE` to do conditional code. We avoid checking for
