doc-astextplain: Simple wrapper around antiword to also cat non-msword documents

Бывают .doc файлы в которых идёт plain-text и antiword на них вылетает с
ошибкой.

bin/doc-astextplain

+#!/bin/sh
+# dump a .doc in astextplain style
+
+# unoconv -f txt --stdout $1
+# antiword $1
+
+err=`mktemp -t doc-astextplain.err.XXXXXX`
+
+antiword "$1" 2>"$err"
+r=$?
+
+if [ "$r" != 0 ] && grep -q "is not a Word Document" "$err" ; then
+	# it's just a plain-text .doc
+	cat "$1"
+	r=$?
+else
+	cat "$err" 1>&2
+fi
+
+rm "$err"
+exit $?
