BestKnownLinearCode(24,12,2); returns
a linear [24,12,6]4..8 U|U+V construction code
which is clearly inferior to the extended Golay code

I think this is fixed, at least I get this with the current guava version:

gap> BestKnownLinearCode(24,12,2);
a linear [24,12,8]4 extended binary Golay code over GF(2)

In fact I cannot reproduce this issue with any guava version down to 3.12, shipped with GAP 4.5.7, released in 2012. Huh?
