It wasn't really a question, and the fact that you had mentioned that the
solution to the problem might be language dependent did register with me.
I think its a pity that you chose to answer in what appears to be a rather

standard emacs indenting would not suit me. Perhaps I should have mentioned
this.

Thanks for this.
I'll need to read it and understand it before I use it, but it looks like a
good starting point.
