From 77f7f822889411bfede0507dd60aebf11edb2849 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Tue, 10 Jan 2012 14:32:06 -0500 Subject: attr: drop misguided defensive coding In prepare_attr_stack, we pop the old elements of the stack (which were left from a previous lookup and may or may not be useful to us). Our loop to do so checks that we never reach the top of the stack. However, the code immediately afterwards will segfault if we did actually reach the top of the stack. Fortunately, this is not an actual bug, since we will never pop all of the stack elements (we will always keep the root gitattributes, as well as the builtin ones). So the extra check in the loop condition simply clutters the code and makes the intent less clear. Let's get rid of it.
