Sorry for my late response, I am still trying to catch up with an
ever-growing inbox after trying to pretend to be on vacation.

Your argument is a strong one, and I will try to re-roll, folding the
functionality to find the unique prefixes into `add-interactive.c` while
trying to reuse the already-sorted list for the lookup by prefix.

As to the multi-byte UTF-8 characters: you're right, that code has a
bug. The intention was to require only single-byte characters in the
prefix, for simplicity.

Thanks,
Dscho
