[ Sorry, sent it a bit precipitously. ]

In practice it's rare for completion candidates to start with combining
characters, so it's maybe not a bad tradeoff to dump that burden on the
few completion tables where we know it's more likely to occur.

Still, if it can be done cheaply enough in `minibuffer.el`, it's much
better, because the poor souls writing those completion tables are
unlikely to be familiar with the issue and how best to circumvent it.
