All examples I gave (and the example with which this bug thread started) were about completion candidates displayed at EOB with an overlay, and I mentioned icomplete and ido several times. I never claimed that in the case you mention the display should start at BOB. >> In general I don't know, but for the usecase with which this bug >> started (namely displaying completion candidates after point with an >> overlay), the answer is clearly and definitely no.

And I'm proposing a solution that would work in all cases, not just in the simplest ones. Let's continue this discussion in bug#43572, where I eagerly wait for your comments.
