'''
Unwraps lines based on line length and punctuation
supports a range of html markup and text files
the lookahead regex below is meant look for any non-full stop characters - punctuation
characters which can be used as a full stop should *not* be added below - e.g. ?!“”. etc
the reason for this is to prevent false positive wrapping. False positives are more
difficult to detect than false negatives during a manual review of the doc
This function intentionally leaves hyphenated content alone as that is handled by the
dehyphenate routine in a separate step
