OK. I pushed it to gawk-4.2-stable.

Yes -- it's slightly fragile. I must confess that I personally think having an
abort statement in the language would be a nice addition (simply because it
would save typing and reduce code clutter), but I'm pretty sure you will
adamantly resist this. :-) It seems that TAWK has this, and you document it in
your O'Reilly book about sed & awk. I wonder whether it could be implemented in
an extension library. I suppose the function could simply call 'exit', and that
would eliminate the ordering fragility of using an include library. The problem
with using a library is that we lose the ability to retain the default exit
status if none is provided to the function...
