Expunge occurrences of `setq' with an odd number of arguments.
* lisp/apropos.el (apropos-documentation):
* lisp/obsolete/complete.el (PC-include-file-all-completions):
* lisp/progmodes/compile.el (compilation-goto-locus):
* lisp/vc/vc-cvs.el (vc-cvs-parse-root): (twice)
Insert missing nil at end of `setq' forms.
* lisp/emacs-lisp/bytecomp.el (byte-compile-file-form-autoload): Remove an
erroneous trailing variable name from a setq, thus allowing a compilation
properly to track functions not defined at runtime.
