Original GitHub issue: https://github.com/rivo/tview/issues/251

msg := "123456789012345678901234567890"
fmt.Printf("wrapping %s: %#v", msg, tview.WordWrap(msg, 10))

results in

wrapping 123456789012345678901234567890: []string{"12345678901", "2", "3", "4", "5", "6", "7", "8", "9", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "0"}

The function docs don't actually mention breaking up words, but the code is trying to do something with it. Suggest that the above should result in

wrapping 123456789012345678901234567890: []string{"1234567890", "1234567890", "1234567890"}

Thanks!

Thanks. Yeah, that seems to be wrong. I'll fix it but it will need to wait a bit because I'll be offline for the next three weeks.

I believe I was able to fix it. This is way more difficult than it seems at first.

Awesome. Yeah, word-wrapping is a lot harder than it seems. Why Knuth took all those years off from writing his books to write TeX 😃

Haha! Right. I actually think that the current version won't be the last. Once rivo/uniseg#2 is implemented, I'll have to review my code here (and probably completely rewrite it again).
