Though in the specific case of xrdb, the calls only check if the return
value is -1 or not, so being off by one doesn't matter here, I've gone
ahead and fixed this, and the other issues you raised, so that it's
correct if this gets copied into more apps or the callers get modified
in the future.

Thanks for the review, revised patch follows.
