Revise fix for bug 32178 (spaces at end of log msg). The loop in the earlier patch would invoke undefined behavior in two ways: First, it would check whether it was looking at a space before it checked whether the pointer was in-range. Second, it would let a pointer reach a position _before_ the start of a string, which is not allowed. I've removed the assertion about empty messages: empty messages can be their own warning IMO. I've also added tests for this formatting code, to make sure it actually works. 2020-10-28 14:39:21 +01:00			`32178; bugfix on 0.1.1.1-alpha. Based on a patch by Amadeusz Pawlik.`
