    // Delete all the characters till a complete word was deleted:
    /*
     * What to do: We delete until we find a separator (the function
     * isBackWordStopChar). Note that we MUST delete a delete a whole word!
     * So if the back-word starts at separators, we'll delete those, and then
     * the word before: "test this,       ," -> "test "
     */
    // Pro: same as desktop
    // 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 "
     */
    // Pro: Supports auto-caps, and mostly similar to desktop OSes
    // Con: Not all desktop use-cases are here.

    // For now, I go with option 2, but I'm open for discussion.

    // 2b) "test this, " -> "test this"
