Parsing indented structures (again)

Hi Adrian

It works now, so thanks for the solution (and so quickly). :)
I could tell it wasn't being called, since at one point I had printf
statements in amongst the various actions.  I just couldn't think
why.  It hadn't occurred to me that the scanner action was yanking it
away before that point. In hindsight it was a little obvious.

Is it possible to embed an action in another? As in:

'ina:' double_on_line => {term;array[0] = atof(buffer);};

I am assuming not, as I can't find it in the manual. It would just be
a little neater than the if statements I have now in all the actions,
but ...
