+Subject: [PATCH 8/8] hush: Remove Ctrl-C detection in loops
+Organization: Addiva Elektronik
+
+Assume that the original intent was to emulate SIGINT to a shell. This
+only works as expected if the loop in question is the ouermost, and
+last, statement. In all other cases, it completely breaks the expected
+execution flow. It more or less resurrects Visual Basic's "On Error
+Resume Next".
+
+Disable this behavior and delegate the problem of loop termination to
+the writer of the script instead.
