+#
+# Test whether a .for loop can be used to generate multiple .endif
+# directives to close nested .if directives.  Depending on the exact
+# implementation, this might have been possible.
+#
+# If it were possible, the 3 .if directives would perfectly match the
+# 3 .endif directives generated by the .for loop.
+#
+# After the "included file" from the .for loop, the 3 .if directives
+# are still open.
+#
+# See For_Run and ParseReadLine.  Each .for loop is treated like a separately
+# included file, and in each included file the .if/.endif directives must be
+# balanced.
