I've started working on a PHP test suite in my fork. Right now I'm most interested in tests for the ellipsize_to_word function.

It would be great if you could dump some notes in a comment here on test cases you use for this function. Even just some examples of original+truncated version for what you expect the function to do in all the edge cases would be useful. Thanks!
