     * isBackWordStopChar). Note that we MUST delete a delete a whole word!

     * the word before: "test this,       ," -> "test "

    // Con: when auto-caps is on (the default), this will delete the
    // previous word, which can be annoying..
    // E.g., Writing a sentence, then a period, then ASK will auto-caps,
    // then when the user press backspace (for some reason),
    // the entire previous word deletes.

    // 2) Or we delete all the characters till we encounter a separator, but
    // delete at least one character.

     * What to do: We delete until we find a separator (the function
     * isBackWordStopChar). Note that we MUST delete a delete at least one
     * character "test this, " -> "test this," -> "test this" -> "test "
     */
