This is the cause for an issue in Hyphenator.js: https://code.google.com/p/hyphenator/issues/detail?id=194
To handle orphans upon hyphenation (one syllable or one word on a new line) Hyphenator.js can put a non-breaking-space between the last two words. And these are actually found by a not so intelligent RegExp that doesn't match if there are white-space-chars after the last word. So it really matters (besides some poor programming on my side ;-).
I didn't know if this was an intended behavior.
