Subject: Avoid leading zeroes on internally generated random seeds, _just_ in
X-Git-Url: https://git.distorted.org.uk/~mdw/sgt/puzzles/commitdiff_plain/97c44af328d9279dddd513001ff7c7d22c001c3c

Avoid leading zeroes on internally generated random seeds, _just_ in
case they confuse anyone who expects the same seed without the
leading zero to be equivalent.
