* tests/mixed (sizes): Fix misplaced "&& break" that made us test
only with a size of 0, rather than all sizes in 0..64.
for i in 0 1 2 3 4 5 6 7 8 9 a; do in_str="$in_str$in_str" ;done
# Start with some small sizes. $(seq 64)
-sizes=$(i=0; while :; do echo $i; test $i = 64; i=$(expr $i + 1) && break; done)
+sizes=$(i=0; while :; do echo $i; test $i = 64 && break; i=$(expr $i + 1); done)
# gzip's internal buffer size is 32KiB + 64 bytes:
sizes="$sizes 32831 32832 32833"
