Lout and prg2lout : mixing code and filled text in Python

[Jeff Kingston]

Fixed for next release.  I discovered that Lout escape comments for Python
(beginning, by analogy with the other languages, with #@) had been left out
of prg2lout by mistake.  After adding them I was able to get this to work
without any problems:

    @ID @Python {
    import Html;
    #@@ID ragged @Break {
    address@hidden is pretty clever -- it's a long sequence of lines which
    address@hidden on the fact that escape comments are passed through
    #@@I prg2lout absolutely raw, and hence multiple lines of them
    address@hidden be given provided the whole assembly makes sense.
    address@hidden
    }

This same arrangement works in any language.  I've documented it,
including why it has to be done this way, in the relevant section
of the User's Guide.
