FILL PARAGRAPH

 Fills (reformats) the current paragraph, so that the maximum number of
 words fits on a line according to the margins of the buffer.

 Typically, you use FILL commands to rewrap text after erasing or removing
 text or to reformat text after setting new margins or paragraph indent.

 Steps:

    1.  Put the cursor anywhere in the paragraph you want to fill.

    2.  Use the FILL PARAGRAPH command.

 o  The cursor then moves to the end of the paragraph.  A "paragraph" is
    bounded by any of the following:

       Blank lines      Top or bottom of the buffer
       Page breaks      RUNOFF commands (such as .Blank)

 o  FILL commands erase tabs and spaces at the start and end of a
    paragraph, but do not affect tabs and spaces in the middle.
