From 79bbc7fb078f8cabe04020c4619be9b571371398 Mon Sep 17 00:00:00 2001 From: Johannes Sixt Date: Mon, 22 Sep 2008 13:03:25 +0200 Subject: [PATCH 1/3] git-remote: do not use user input in a printf format string 'git remote show' substituted the remote name into a string that was later used as a printf format string. If a remote name contains a printf format specifier like this: $ git remote add foo%sbar . then the command $ git remote show foo%sbar would print garbage (if you are lucky) or crash. This fixes it.

This in the end did not end up solving any of my personal problems, but it might be a useful cleanup patch nevertheless.
