[why]
Instead of redistributing the line gap we remove it. At least when HHEA or TYPO metrics are used.
It's ok with WIN metrics.
[how]
If we have negative numbers for a gap and want to add more to it, where 'add' means 'make it more', we must of course subtract the value.
But baseline-to-baseline code into function so we can check it after all our gymnastics for correctness. It means the metrics.
[note]
Also correct out-of-sync comment.
