From 47e5c0ca2cabb406518dda5c09432dc996f7ef2b Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Wed, 28 Jun 2006 12:45:27 +0200 Subject: [PATCH] Save errno in handle_alias() git.c:main() relies on the value of errno being set by the last attempt to execute the command. However, if something goes awry in handle_alias(), that assumption is wrong. So restore errno before returning from handle_alias().
