 * There is a minor undocumented bug in Dump().  It calls Justify() in the

 * sentence word (typical) and ends just one blank before the margin
 * (rare).  This results in one blank being inserted in the line when it's
 * not necessary.  It happens because the two trailing blanks after the
 * word cause an "ordinary" line dump before Fill() sees the next line and
 * knows it has an end of paragraph.  WARNING:  The situation would be

 * after wordnext is advanced (and maybe wrapped around).  New elements
 * are "allocated" using wordnext, a pointer that is wrapped around as
 * needed.
 *
 * inlinenum and incolumn track the current input line and column per
 * paragraph.  outlinenum tracks the next line to print.  All are base 1,
 * but inlinenum is preset to zero at the start of each paragraph.
