Still there is an academical interest if this can be done with sed.
Apart from the s/x/y/num that must go from left to right (so can hardly be used on x$,
there is x\{num\}, a special case of x\{min,max\}.
Modified the previous idea, and for Unix sed replaced some ; by newline:
Code:
NB=14
echo "Mary walks at the park every day with her children" | sed '
:A
/ \{'"$NB"'\}$/b
s/$/ /;bA'

NB instead of newlines one can use several '-e line':
Code:
echo "Mary walks at the park every day with her children" | sed -e ':A' -e '/ \{'"$NB"'\}$/b' -e 's/$/ /;bA'

QVBoxLayout(3qt)														  QVBoxLayout(3qt)

NAME

       QVBoxLayout - Lines up widgets vertically

SYNOPSIS

       #include <qlayout.h>

       Inherits QBoxLayout.

   Public Members
       QVBoxLayout ( QWidget * parent, int margin = 0, int spacing = -1, const char * name = 0 )
       QVBoxLayout ( QLayout * parentLayout, int spacing = -1, const char * name = 0 )
       QVBoxLayout ( int spacing = -1, const char * name = 0 )
       ~QVBoxLayout ()

DESCRIPTION

       The QVBoxLayout class lines up widgets vertically.

       This class is used to construct vertical box layout objects. See QBoxLayout for more details.

       The simplest use of the class is like this:

	       QBoxLayout * l = new QVBoxLayout( widget );
	       l->addWidget( aWidget );
	       l->addWidget( anotherWidget );

       <center>
								     [Image Omitted]

       </center>

       See also QHBoxLayout, QGridLayout, the Layout overview, Widget Appearance and Style, and Layout Management.

MEMBER FUNCTION DOCUMENTATION

QVBoxLayout::QVBoxLayout ( QWidget * parent, int margin = 0, int spacing = -1, const char * name = 0 )
       Constructs a new top-level vertical box called name, with parent parent.

       The margin is the number of pixels between the edge of the widget and its managed children. The spacing is the default number of pixels
       between neighboring children. If spacing is -1 the value of margin is used for spacing.

QVBoxLayout::QVBoxLayout ( QLayout * parentLayout, int spacing = -1, const char * name = 0 )
       Constructs a new vertical box called name name and adds it to parentLayout.

       The spacing is the default number of pixels between neighboring children. If spacing is -1, this QVBoxLayout will inherit its parent's
       spacing().

QVBoxLayout::QVBoxLayout ( int spacing = -1, const char * name = 0 )
       Constructs a new vertical box called name name. You must add it to another layout.

       The spacing is the default number of pixels between neighboring children. If spacing is -1, this QVBoxLayout will inherit its parent's
       spacing().

QVBoxLayout::~QVBoxLayout ()
       Destroys this box layout.

       The layout's widgets aren't destroyed.
