CENTER LINE

 Centers a line of text between the current margins of the buffer, by
 inserting spaces at the start of the line.

 Steps:

    1.  Put the cursor anywhere on the line you want to center.

    2.  Use CENTER LINE (or with the WPS keypad, press GOLD-C).

 Usage notes:

 o  The cursor moves with the line, remaining on the same character as the
    text moves.  If you are on a blank line, CENTER LINE moves the cursor
    to the center column between the left and right margins.

 o  CENTER LINE deletes tabs or spaces at the start and end of a line---and
    then adds spaces at the start--but does not affect spaces and tabs in
    the middle of a line.
