Serhiy Storchaka added the comment:
Current regex produces insane result.
$ ./python -c "import textwrap; print(textwrap.wrap('this-is-a-useful-feature',
width=1, break_long_words=False))"
['this-', 'is-a', '-useful-', 'feature']
Antoine's regex produces more correct result for this case: ['this-', 'is-',
'a-', 'useful-', 'feature']. But this is not totally correct, one-letter word
should not be separated. This can be easy fixed.
