* InputHelper returns full words, not just suffixes. I liked the fact that suffixes made it impossible to violate the "all matches will start with your prefix" invariant, but in practice it was fiddly to work with. * add ih.when_wordlist_is_available(), so the frontend can block (after claiming the nameplate) until it can return a complete wordlist to readline. This helps the user experience, because readline wasn't really built to work with completions that change over time * make the Wordlist responsible for appending hyphens to all non-final word completions. InputHelper remains responsible for hyphens on nameplates. This makes the frontend simpler, but I may change it again in the future if it helps non-readline GUI frontends. * CodeInputter: after claiming, wait for the wordlist rather than returning an empty list * PGPWordList: change to match This has the unfortunate side-effect that e.g. typing "3-yucatan-tu TAB" shows you completions that include the entire phrase: "3-yucatan-tumor 3-yucatan-tunnel", rather than only mentioning the final word. I'd like to fix this eventually.
