Bug#4293: mawk doesn't report an error on full filesystems

[Herbert Thielen <Herbert.Thielen@lpr.e-technik.tu-muenchen.de>]

Package: mawk
Version: 1.2.2-1

Mawk doesn't report an error when writing to a full filesystem:

	$ mawk '{print}' < /etc/motd > /dev/full
	$ echo $?
	0

Probably no write error is catched. Gawk does it's job correct:

	$ gawk '{print}' < /etc/motd > /dev/full
	gawk: cmd. line:1: (FILENAME=- FNR=9) warning: error writing standard output (No space left on device)

Regards
	Herbert.
