+Line-wrapping may be done with the | wrap filter.  The first
+parameter is the number of characters to target for the string
+width.  The second parameter is the wrapping algorithm to use.
+The third parameter is the prefix to use for the second and
+subsequent wrapped lines.  One use for this is indentation
+with spaces.
+
+Available wrapping algorithms:
+
+once    = Wraps a line just once
+default = Keeps wrapping a line until no more wraps are possible
