Don't rely on RS = "0" to swallow the whole input as a single

record, this is not portable: mawk and nawk understand it as RS =
"".  gawk understands it as expected.

* autoconf.sh (translate_awk::BEGIN): No longer change RS.
(translate_awk::body): Move to the END.
Instead, accumulate the input in `request'.
