By the way, the reason I harp on this particular example is because
I have seen a LOT of code fail due to exactly this (and the previous)
construct.  getchar() returns an int; therefore it is that int value
that should be tested against EOF before any possible conversion to a
char (which may or not be signed).  It is easy to get this right..
