Yup.  It's a pretty odd design decision, though -- I wonder whether it
this happened on purpose or whether that was just the simplest way to
implement this.

I've added Juri to the CCs; perhaps he can clarify.

(The problem is that if you ask to replace "foo.*bar", and you have

foo bar bar

then `query-replace' will match the entire line, and then filter out
that match (given that we have a rectangular region that covers just
"foo bar") and not replace anything.)
