No, I wouldn't.  I don't like that translation for two reasons:

1. It loses information that may be useful.  In the future we could
want to implement a feature whereby the user can toggle the
lax-whitespace-matching behavior during an Isearch session.  In fact I
think it would be a good feature (and ISTR that Drew proposed some
time ago).  That feature would not be possible if we change the text
that the user supplies to search for.

2. It is less surprising and more clean to me to see in the echo area
exactly the text I'm supplying, without translations of any kind.
