I figured it out. Readline uses what the user typed as the common prefix
if there are multiple matches that don't share a prefix at all. It's been
like that for many years; I'm not going to change it before bash-4.4. The
common prefix (and its length) is what is used to determine whether or not
the prefix display length code is active.
I'll look at changing this after bash-4.4 is released. That's essentially
the cause of all the strange behavior, which is fairly rare.
