Well, I think all these commands would make sense during a
query-replace, for adjusting the search (that is taking place as part
of the replace operation) in the same way that they would adjust an
Isearch.  So, why not binding them in `query-replace-map'?  That would
make Isearch and query-replace more coherent.

IMO, here `M-e' would be better, for consistency with Isearch.

That's fine, but it's not the case I'm talking about.

It seems that my English is worse than I thought :)  I'll try to
explain it in yet another way: I'd like to configure my Emacs so that,
at any moment, an Isearch would find exactly the same matches than a
query-replace (with the same search string, of course), and without
the need to start the query-replace from an Isearch.

One way to achieve that goal would be to define a special value for
`replace-lax-whitespace' whose meaning be "use the current value of
`isearch-lax-whitespace'".
