#C Line Puffer, with extensible width. (Width shown: 33)
#C
#C The width is defined by the length of the first
#C free-standing line in the puffer's plume.  The
#C formula for this is 12n+1-s, where n is the number of
#C middle segments, and s is the number of cells covered
#C by the little 3-cell, 5-unit puff-suppressors on the
#C upper edge of this otherwise symmetrical pattern.
#C
#C Here, n=4, and s=6+5+5.  The Y-shaped puff-
#C suppressors can have 5, 6, or 7 units of spacing
#C between them, or between one of them and the end.
#C You only need 2 or 3 such suppressors to produce any
#C puffer width.
#C
#C Notice that placing random debris behind the puffer
#C sometimes affects the plume permanently - even
#C turning it asymmetrical if the debris was
#C asymmetrical.  It also affects the period of the
#C puffer, that is, the number of generations it takes
#C to repeat.  By increasing the width, the period can
#C be made to rise exponentially, surpassing 10^6 at a
#C width of only about 70.
