I'm familiar with wordwrap, but is there a similar function which will limit the size of a 'word'?   In other words, is there a built-in function which will turn this:

asdfasdfasdfasdfsafsadfasdfasdfsadfasfsafsadfsadfsadfasfsafsafsafsafsadfsadfsadfsadfasfasfsdsdafsadfsadf

into this:

asdfasdfsafdsafdsafdsadfsdaf
asdfasdfsadfsadfsadfsadfsdaf
asdfasdfsadfsafsadfasfsadfsda
saddfsadfsafsafsafsafsdfsadf
