Johannes Sixt'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.
