21.1Srillig#
31.1Srillig# Test whether a .for loop can be used to generate multiple .endif
41.1Srillig# directives to close nested .if directives.  Depending on the exact
51.1Srillig# implementation, this might have been possible.
61.1Srillig#
71.1Srillig# If it were possible, the 3 .if directives would perfectly match the
81.1Srillig# 3 .endif directives generated by the .for loop.
91.1Srillig#
101.1Srillig# After the "included file" from the .for loop, the 3 .if directives
111.1Srillig# are still open.
121.1Srillig#
131.1Srillig# See For_Run and ParseReadLine.  Each .for loop is treated like a separately
141.1Srillig# included file, and in each included file the .if/.endif directives must be
151.1Srillig# balanced.
