cache.h: put single NUL at end of struct cache_entry
Since in-memory index entries are allocated individually now, the variable slack at the end meant to provide an eight byte alignment is not needed anymore. Have a single NUL instead. This saves zero to seven bytes for an entry, depending on its filename length. Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>
