[PATCH 2/4] push: allow configuring default for --confirm

[Owen Taylor <otaylor@redhat.com>]

From: Owen W. Taylor <otaylor@fishsoup.net>

A new configuration variable push.confirm sets the default
behavior for whether 'git push' should show prompt the user
interactively before proceeding to update refs.
