// If one keyword is a prefix of another, and the next CharT in the input
// might match another keyword, the algorithm will attempt to find the longest
// matching keyword. If the longer matching keyword ends up not matching, then
// no keyword match is found. If no keyword match is found, __ke is returned
// and failbit is set in __err.
// Else an iterator pointing to the matching keyword is found. If more than
// one keyword matches, an iterator to the first matching keyword is returned.
// If on exit __b == __e, eofbit is set in __err. If __case_sensitive is false,
// __ct is used to force to lower case before comparing characters.
// Examples:
// Keywords: "a", "abb"
// If the input is "a", the first keyword matches and eofbit is set.
// If the input is "abc", no match is found and "ab" are consumed.
