Subject: Initialize final byte of cryptState_t::decrypt_history, too.
X-Git-Url: http://git.code-monkey.de/?p=umurmur.git;a=commitdiff_plain;h=00137368a0955dc05c38b122971cae555689267f

Initialize final byte of cryptState_t::decrypt_history, too.

This fixes an off-by-one error in CryptState_init() which would
leave the final byte of decrypt_history uninitialized.
