Unfortunately not portable:
$ /usr/bin/diff -a foo bar
/usr/bin/diff: illegal option -- a
usage: diff [ -C n ] [ -S name ] [ -bcefhilnrstw ] dir1 dir2
diff [-C n ] [ -bcefhintw ] file1 file2
diff [ -D string ] [ -biw ] file1 file2
Perhaps Stefan can run the test manually and get us a readable diff.
