> I do not expect him to return a “new man”.

A *lot* of what Linus says and does ranges between good and excellent.
The number of times he uses inappropriate language are relatively few - but they have an effect out of proportion to their size (which is expected given Linus' power and position).

So Linus doesn't need to become a "new man", he just needs a little bit of a shave - file down those few rough edges a bit.
