Great!  I would seem to have fans everywhere. :-)

I think that's pretty sensible.  I don't care too much one way or
another as to whether or not there's a separate 'decode_line_2'
function to do the parsing, but the general idea of setting various
necessary flags first before doing any decoding sounds good to me.

For now, I want to worry about breaking up the existing code into
separate functions first (I'm already giving Elena enough to worry
about as it is, I think), but it sounds like, once that phase is done
and we can actually understand what decode_line_1 is doing, we'll want
to start rewriting functions, changing the existing reorganization.
So hold off on your patch until then, and then we can talk.
