PrintW - print a long string, breaking it at the last space or hyphen before col. 79

If you test your code, always test the limits.
empty strings, long strings, etc.
Yours does not like long lines without dashes or spaces

Not sure I understand @mdijkens...  I thought word-wrap meant to wrap the next word if the line was too long. Are you refering to extra-long words, and splitting them at a syllable with a hiphen? Long strings are handled ok with my line-wrap, but, no it doesn't split words. And as for empty strings... why would you wrap them?
