From 45bd0c808d2a89254ee50807a99b7cf1147aa6d7 Mon Sep 17 00:00:00 2001 From: Jakub Narebski Date: Mon, 30 Oct 2006 22:29:06 +0100 Subject: [PATCH] gitweb: Secure against commit-ish/tree-ish with the same name as path Add "--" after or argument to clearly mark it as or and not pathspec, securing against refs with the same names as files or directories in [live] repository. Some wrapping to reduce line length as well.
