From 7886cfa08054046a7a82726be4b8c109b2ba1344 Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Fri, 8 May 2015 10:02:00 +0200 Subject: [PATCH] bundle: verify arguments more strictly The `verify` and `create` subcommands of the bundle builtin do not properly verify the command line arguments that have been passed in. While the `verify` subcommand accepts an arbitrary amount of ignored arguments the `create` subcommand does not complain about being passed too few arguments, resulting in a bogus call to `git rev-list`. Fix these errors by verifying that the correct amount of arguments has been passed in.
