[LyX/master] Forgot in previous commit to deal with case. As I'm doing it now, it's easy to use the existing docstring routine, so I've commented out the string version of lowercase I had introduced. I've left the code in case someone else needs it later.

    Forgot in previous commit to deal with case. As I'm doing it now,
    it's easy to use the existing docstring routine, so I've commented
    out the string version of lowercase I had introduced. I've left the
    code in case someone else needs it later.
