So... maybe it's not a general problem, but here is a buggy case. LDPE Edger2 with default settings generates unmatched lines everywhere (****). With increased precision value (from 0.001 to 1), no unmatched line is created between quads (so precision parameter does have an influence)... but no condline either!
(****) Default precision value of LDPE Edger2 is 0.0001, which is pretty low. Regular Edger2 default is 0.001, a value validated by years of usage...
