[issue22687] horrible performance of textwrap.wrap() with a long word

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Thank you David. If splitting single letter surrounded with hyphens is desirable, here is more complicated patch which does this. It deviates from original code more, but it doesn't look break any reasonable example.

Aren't ['this-', 'is-a', '-useful-', 'feature'] and ['what-d', "'you-", 'call-', 'it.'] obvious bugs?
