Almost, but it doesn't match his description. Consider a few edge cases:
"foo bar" is changed to "foo bar"
This is due to the fact that you're only using a positive lookahead to
determine if it's a lone space. You must take into account what's before
the space, as well, to determine if it's a lone space.
"foo . bar" is changed to "foo .bar"
This is due to the fact that you're doing the lookahead on \w when it should
be on \S, or possibly [^ ].
