From f0f04ddd70aa3260f5282227de264653ac36fabe Mon Sep 17 00:00:00 2001 From: Andreas Sandberg Date: Mon, 16 Oct 2017 15:36:41 +0100 Subject: util: Remove support for hg patches in patch creation script Simplify the patch creation helper script by removing support for automatic conversion to Mercurial's patch format. We no longer use Mercurial as a primary repository, so this support is not likely to be needed again.
