It's easy to get rid of the `x` occurrence that *binds* (in the
expansion) by changing `internal--build-binding' - the name of the
binding symbol doesn't matter in this case.

Then I guess we could use this `&interpose' Edebug spec but it's
undocumented and not really trivial to understand.  But looks like the
right tool for this case... (?)

Michael.
