Omitting m in qfminim


When I omit m in qfminim the documentation
says that all vectors are stored.

However in practice we have:


? matsize(qfminim(matid(10),5,,2)[3])
%11 = [10, 200]
? matsize(qfminim(matid(10),5,10000,2)[3])
%12 = [10, 6482]
? 


Furthermore qfminim only stores one of the vectors +X, -X,
but it still could collect X, 2*X, 3*X, ... depending on b and m.
would it not be preferable to store at most one of { k*X | k integer} ?
Depending on the inputs a lot of space could be saved without loosing
information ?
