Well, I think I'm going to commit it with the "a" because (i) this
definitely seems better than what was there before in any case and (ii)
hitting "ESC" and "." after typing the start of the line, which is my
naive way of getting it to repeat, does repeat what I just inserted
because of vi's quirk of backing up a character when leaving insert
mode.  Obviously I'm not claiming this is the end of the matter.

This remains the case.  I will not be able to guess what vi mode's many
oddities are supposed to do.

I'm not hearing much in the way of knowledgeable direction for the
completion issue.  It probably needs some hook trying out to see
if it works.
