Many thanks to all - I ended up doing it in Perl, actually.
perl -e ' ($file1, $file2) = @ARGV; $printed = 0; open F2, $file2;
while (<F2>) { $h2{$_}++ }; $count2 = $.; open F1, $file1; while
(<F1>) { if (! $h2{$_}) { print $_; $printed++; } } $count1 = $.; warn
"\nRead $count1 lines from $file1 and $count2 lines from
$file2.\nPrinted $printed lines found in $file1 but not in $file2\n\n"
' 1.txt 2.txt > 3.txt
