Yes, it's a very good concern, which I share. :-)

I have been trying to avoid making any changes to areas 
where there is still stuff to merge.

I only start changing once there isn't anything else to merge
[in the case of @encode and similar, I have already merged 
everything.  In the case of the C parser/lexer, it's impossible
to merge anyway since the apple branch uses the old parse.in 
parser ;-)]

Thanks
