Optimise 'while' bodies for effect

[Mattias Engdegård]

Optimising the body of 'while' forms for effect (proposed patch attached) finds 
the following:

In nnheader-find-nov-line:
~/emacs/lisp/gnus/nnheader.el:449:32:Warning: value returned from (= (setq num
    (read cur)) article) is unused

In ldap-search-internal:
~/emacs/lisp/net/ldap.el:528:30:Warning: value returned from (1+ numres) is
    unused

In org-babel-screen-test:
~/emacs/lisp/org/ob-screen.el:120:4:Warning: value returned from (format
    "org-babel-screen: File not readable yet.") is unused

Not much, perhaps, but worth doing anyway?
