bug#3437: Add patch to bug #3437

Here's a patch that does what I mean. It changes the original "if" form
to "cond" form and adds a condition branch for the case when the point
is at the end of logical line:

    (cond ((eolp)
           (goto-char (1+ (point))))
          ...)

The semantics of the original "if" form is reproduced in the place of
"..." above, that is, as other "cond" branches.
