def wordWrappers.wrap_onspace	(		text,

A word-wrap function that preserves existing line breaks
and most spaces in the text. Expects that existing line
breaks are posix newlines (\n).

def wordWrappers.wrap_onspace_strict	(		text,

Similar to wrap_onspace, but enforces the width constraint:
words longer than width are split.
