I'll have to create some further test cases for different scenarios of overlapping/adjacency behavio= r of both matching lines and non-matching lines to make sure that's right. This is likely a really strange corner case that probably won't have any practical application, but consistency is good. --=20 You are receiving this mail because: You are the assignee for the bug.=
