That bit is type safe; IIRC, when you add an integer to a pointer, it gets
multiplied by the appropriate thing (1, in this case). I just think it's
bad style, unaesthetic, and less clear than the loop. If the possible
increased speed of strlen matters, then I think
t = &s[strlen(s)];
is more obvious about what it's doing, then though it requires more
punctuation.
