From 06ac6e455e0b54863972e8a7ba9707e3e56a87f2 Mon Sep 17 00:00:00 2001
From: Harald Welte <laforge@gnumonks.org>

Subject: Revert "Simplify git checkout, allow branches and commits"

Unfortuately this commit will check out *local* master (i.e. the
previous checkout) rather than the origin/master as it's supposed to
be. This means that ever since merging this patch, our ttcn3 tests
were running some "undefined" stale versions and not current master.

This reverts commit 26565bb729549152ce8fa89f59df02f37c907c27.

Change-Id: Ie6da0f9ea96f11407e38545a6b3cf22ef9cadc25
