This adds a test to ensure that puts is equivalent to putc called in a loop. We don't verify the contents of the message to avoid having to record console output a second time (though that could be added in the future). The globals are initialized to non-zero values to avoid a warning; in particular, the character count is off-by-one (but we always make relative measurements).
