Christian Brabandt 87cdf8f6c4 highlighter: Make sure hi group exists and is valid ... previously we only checked, that the group exists, however if loading a new color scheme, this might lead to the group becoming cleared. That means it still exists, but the highlighting group would not show anything. Therefore, also check that the group is not cleared. closes #1483		2017-06-21 09:19:51 +02:00
