> Fixes a bug whereby 'lzread!' could return more than COUNT.

Hmm... But why is this a bug?  lzread! returns the number of
_uncompressed_ bytes, while COUNT is number of _compressed_ bytes
written, so it's often expected that the former is more than the latter.

(By the way, nice rewrite, I like it much better than my C->Scheme
translation ;p)
