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
