Message wrapping now avoids splitting words

The changes of 4ceea2f0f77a4cd9f140998213fd4b60b7fbae31 truncate every single word that approaches the end of the line. This doesn't really look good, and hinders readability.

This makes messages use `word-break: normal`, which attempts to avoid breaking words, but will break if a word doesn't fit on its own line. This is the default behavior in modern browsers
