From 4d3ab44d26c47d100cec39d0ef9ed9746eb7e454 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ren=C3=A9=20Scharfe?= Date: Mon, 28 Jul 2014 20:31:57 +0200 Subject: [PATCH] use xgetcwd() to set $GIT_DIR Instead of dying of a segmentation fault if getcwd() returns NULL, use xgetcwd() to make sure to write a useful error message and then exit in an orderly fashion.
