+Bug-Description:
+
+There were cases where patch 16 reaped process substitution file descriptors

+Bug-Description:
+
+In certain cases, bash does not perform quoted null removal on patterns
+that are used as part of word expansions such as ${parameter##pattern}, so
+empty patterns are treated as non-empty.
