read: Avoid possible NULL dereference in getNthPrevCFromInputFile()
Also, don't perform subtractions to check pointer bounds, to avoid
unsigned value wraparound. This is very unlikely as it would either
mean a very large `nth` value or a very small value for the current
line pointer, but better safe than sorry.
