According to http://www.w3.org/TR/css3-text/#word-break0
word-break: break-all;
...does not do the same as word-wrap (which is now renamed to overflow-wrap) because even small words may be broken when they are at the end of the line. But it works.
In some rare cases hyphen: auto; may bring you better results, but only if your long word is included in a dictionary the browser uses.
