ager@chromium.org ff4e9ea134 Make sure that the body of the function created by calling Function is
on a line of its own.  This allows the body to be terminated by a
single-line comment.

Also, make sure to set the name of the function to anonymous after the
fact so that recursion through the name anonymous is not allowed and
so that global variables called anonymous are not shadowed.

This is a fix for http://code.google.com/p/v8/issues/detail?id=85
