Yes, "emacs -Q" here.  And it's not a surprise you have those missing
candidates in the index, that's how I can see them ;-)

Are you sure you did 'i home TAB' in the latest manual, though?

By "feature" I meant that it replaces "home" which I typed by "HOME",
for whatever reasons.  The _only_ reason that I could accept as
legitimate is if _all_ completion candidates started with an
upper-case "HOME".  But that's not what we have here.  So it looks
like some attempt at being smart is misfiring.

HOME _is_ used, except that completion removes duplicates (I guess).
As for HOSTNAME -- why should it be used?  I don't see it used here.

No, the entry that revers to "Moving Point" is also capitalized.
