From 7e4a2a848377241b8fb4f624d1151bbf2f8d5814 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Mon, 26 Dec 2005 12:34:56 -0800 Subject: avoid asking ?alloc() for zero bytes. Avoid asking for zero bytes when that change simplifies overall logic. Later we would change the wrapper to ask for 1 byte on platforms that return NULL for zero byte request.
