Subject: [PATCH] pull: warn on --verify-signatures with --rebase

From: Alexander 'z33ky' Hirsch <[email-masked]>
Date: Wed, 18 May 2016 12:18:27 +0200

Previously git-pull silently ignored the --verify-signatures option for
--rebase.

Sorry it took so long for the update.
I made git-pull warn instead or error and explained why "the
--verify-signatures option does not work for --rebase" in the message.
