Fuzzy matching for Chicken AutoDoc and Completions
Because Chicken allows symbols to be imported with prefixes, and because
'apropos' does not provide any utility to match with the loaded
prefixes, it is difficult to acquire information about prefixed symbols.
This solution hacks around the issue by providing naive
fuzzy-matching. If no match for a symbol can be found then the first
character is dropped and matching is attempted again; the process is
repeated until matches are found or the entire symbol is consumed.
Also removes the (now redundant and slow) geiser-chicken-prefix-delimiters.
