The code goes out of its way to create a special list of parameters in
entry.struct_actual that is just like entry.parameterlist, but with extra
junk. The only use of that information, in check_sections(), promptly
strips all the extra junk back out. Drop all that extra work and just use
parameterlist.
No output changes.
