* move the declaration of flg (with the initializer) to the loop, so
there is no need to reset it to TTY_NORMAL by an 'else' branch.
* use TTY_NORMAL as initializer above, not a magic zero constant
* remove the outer 'if' from this construct:
if (S & (A | B)) {
if (S & A)
X;
if (S & B)
Y;
}
* drop unlikely() as I doubt it has any benefits here. If it does,
provide numbers.
All four make the code easier to read.
