>Description:
	On NetBSD 2.0 and -current, this command line:

		echo hi | awk 'END { print }'

	prints an empty line, and not the last line of the input.

	On NetBSD 1.6.2_STABLE (which uses GNU awk), the last line
	of the input is printed (and the fields are available via
	the positional variables $1 etc.)

	There appears to be support (though only implicit) for the
	GNU awk interpretation of what should be available under
	the END pattern in the SUSv2 specification at

		http://www.opengroup.org/onlinepubs/007908799/xcu/awk.html

	where it is said that NF and NR retains their values from
	the last record seen under the END pattern.

>How-To-Repeat:
	See above.
>Fix:
	Sorry, none supplied.

	However, browsing the code (which I'm not familiar with...)
	it seems to me that getrec() should not commit to zeroing the
	input buffer as the first thing it does.
