add -i: allow prefix highlighting for "Add untracked" as well.

These changes make the automatic prefix highlighting work with the "Add
untracked" subcommand in git-add--interactive by explicitly handling
arrays, hashes and strings internally (previously only arrays and hashes
were handled).

In addition, prefixes which have special meaning for list_and_choose
(things like "*" for "all" and "-" for "deselect) are explicitly
excluded (highlighting these prefixes would be misleading).
