I suppose this is common rule in many languages. And current code supports it
(there is a special code in the regex to ensure this rule).

But the patch shouldn't add a regression.
$ ./python -c "import textwrap; print(textwrap.wrap('this-is-a-useful',
width=1, break_long_words=False))"
Current code: ['this-', 'is-a-useful']
Patched: ['this-', 'is-', 'a-', 'useful']
Just use lookahead assertion to ensure that the hyphen is followed by at least
two letters.
My previous message is about that current code is not always correct so it is
acceptable to replace it with not absolutely equivalent code.
