Coveralls failures are misleading

[obormot]

Those "coverage decreased" failures are bogus and appear when the coverage has not changed at all, which can be confirmed by looking at the detailed report in Coveralls. There should be a setting that can be tweaked to fix this.

I will look into this.
A quick look reveals what coveralls thinks is wrong.

[obormot]

Yes it does report something, but this specific piece of code didn't change => there's no drop in coverage. Perhaps there's a threshold that can be adjusted, like "treat any change below 0.1% as no change"

Here's another example of this. PR #646 - no change in coverage; Coveralls is all over the place.
