+Subject: [PATCH] patch 9.0.2107: [security]: FPE in adjust_plines_for_skipcol
+
+Problem:  [security]: FPE in adjust_plines_for_skipcol
+Solution: don't divide by zero, return zero
+
+Prevent a floating point exception when calculating w_skipcol (which can
+happen with a small window when the number option is set and cpo+=n).
+
+Add a test to verify
