736    @defun copy-tree tree &optional vecp
737    This function returns a copy the tree @code{tree}.  If @var{tree} is a
738    cons cell, this makes a new cons cell with the same @sc{car} and
739    @sc{cdr}, then recursively copies the @sc{car} and @sc{cdr} in the
740    same way.
741    
742    Normally, when @var{tree} is anything other than a cons cell,
743    @code{copy-tree} simply returns @var{tree}.  However, if @var{vecp} is
744    non-@code{nil}, it copies vectors too (and operates recursively on
745    their elements).
