unfold issue - hem

Fixed alongside your hexagon report — this one was the flat pattern unfolder again. With hems mitered on all four sides, the corner cuts were splitting each fold line into fragments and the unfolder anchored on a tiny fragment instead of the full fold — that's why the fold lines came out a fraction of their length and the hem legs landed skewed. It now reads each bend as one full-length fold: your file develops to a perfect square with all four hem fold lines at full length. In the next release (v2.3.8), and your part is in the test suite too. Thanks for both files — they made these easy to nail down.
